SO MUCH ABOUT SHARKS: Cool kinds, anatomy, YOU, and the dogfish shark

I wrote this a long, LONG time ago, and my writing style's become considerably less stiff since then, but sharks are still super-cool, and I wanted to share some of this coolness with you! You can skip to your favorite section if you want (weird kinds of sharks, shark anatomy, shark lifestyle, etc etc)--just scroll down looking for the big words.

INTRO

All sharks are in the kingdom animalia, phylum chordata, and class chondrichthyes, along with chimaeras, rays, and skates. They are classified in subclass Elasmobranchii with skates and rays. The most famous shark is undoubtedly the Great White, popularized by horror movies, but there are over 370 different species of shark of all shapes and sizes, ranging from a small member of the genus Squaliolus (males—6” approx., females—8” approx.) to the massive whale shark (Rhincodon typus) measuring 40 ft. or more. The number of shark species is relatively small, though, compared to the 2,800 different kinds of bony fish. Nevertheless, the shark is a very diverse creature. We would like to give you a brief overview on a few species before going into the general characteristics of all sharks.^{i ii}

NEAT KINDS OF SHARKS

The small smooth dogfish shark (Mustelus canis) averages 3 to 4 ft. in length and is one of the most abundant sharks on the east coast, found in great numbers in the Delaware Bay—more are caught here than all other sharks combined. They leave the area in mid-October, although some are still here by early November and don’t return north until the water rises above 50 degrees Fahrenheit. These common sharks have low, crushing, flat teeth—and a lot of ‘em—and feed mostly on crustaceans like lobsters, crabs, and clams, as well as small fish. ⁱⁱⁱ

One very interesting shark is the Megamouth shark, (Megachasma pelagios, meaning big cave of the sea) considered by some scientists to be one of the oldest and most primitive species within the order Lamniformes. A whole new genus had to be created when it was found. It looks more like a small whale than a shark, with a flabby body, long pectoral fins, and very short dorsal fins, and is thought to have poor mobility and to be less active than whale sharks or basking sharks. Very little is known about this shark; it has only been sighted 27 times. It habits waters all over the world, although the most sightings were seen in the Pacific, and seems to spend daytime in deep waters and night in mid water depths. Its body tapers posteriorly and its head looks big. It’s pretty much white on the bottom and brown on the dorsal surface, darker towards the head, with a whitish band on the snout. It has fifty rows of teeth, females seeming to use fewer rows than males. The largest was 17 ft—males mature by 13 ft and females by 16 ft. It filter-feeds mainly on krill, shrimps, and other such organisms and is fed upon mostly by sperm whales. ^iv

Another unusual shark is the cookie-cutter shark (Isistius braselienus), which is a very small fish that preys upon slow larger fish. It is very aggressive and has been known to take bites out of submarines, taking them for large whales. The cookie-cutter sharks live around larger creatures and take bites out of them as they go along. They frequent deeper waters during the day and mid-waters during the night, making the Megamouth shark easy prey for them.^iv

The Megatooth shark is also of interest, and it is the largest fossil shark known to man, estimated to have reached at least 40 feet and 20 tons, like a very carnivorous whale shark. Carcharodon megalodon is thought to have fed on large fishes and mammals and seems to be the closest “relative” to the Great White shark. Unfortunately, sharks, lacking bones, don’t preserve well and this fossil is known only by its teeth and jaws—but these are REALLY huge, kind of like a REALLY GREAT WHITE. ^{i iv}

Unfortunately we are not writing a book but only a report, and cannot describe the basking shark, the Caribbean shark, the Galapagos shark, the Tiger shark, the Lemon shark, the Nurse shark, the Sand shark, the Sandbar shark, the black tip shark and many others. We hope you have a very slight appreciation for the diversity of subclass Elasmobranchii. Before we move on, though, we HAVE to mention the Great White.

To put it bluntly, Cacharodon cacharias is dumb and antisocial. It does not tell its prey by shape, size or color but by taste, and will attack pretty much anything that splashes on the surface. It feeds primarily on aquatic mammals and occasionally a marine reptile, as well as large fish. It never eats sea otters or aquatic birds—perhaps, like people, they taste awful. It appears to prefer high-energy, fatty foods, kind of like how Americans prefer high-carb McDonald’s meals. For example, the Great White will strip the blubber off of a whale, but not the muscle underneath. The White’s skin is less rough and sand-papery than most other sharks, and is rather smooth. The Great White roams waters all over the world, is most viewable in the wintertime, and hates other Great Whites. If two whites come upon each other from opposite direction, they will both turn and leave. Often when one White wants another to clear out, it will slap the water with its caudal fin, roll over in the water, or leap up and smack itself against the water. These splashings are then detected through the "lateral lines" (specialized organs) of the other shark. The Great White attacks prey in many different ways, sometimes charging it horizontally across the surface, sometimes attacking from below, and sometimes charging it directly vertically with such a force that it leaps out of the water like a dolphin.^{v iv}

^{COOL SHARK ANATOMY}

Despite all this variety, all sharks follow a uniform definition, having one general body pattern and many similarities in lifestyles. We will begin with the shark’s body plan and then move to discussing lifestyles before talking a little on the other members of the class chondrichthyes.

The shark’s skeleton is similar to other fish, but made of cartilage instead of bone. This cartilage is usually hardened by mineral deposits, especially around the vertebrae and the skull, but it does not do well outside of water. The cartilage is lighter than bone, which increases buoyancy. The skeleton is made up of two main areas—the axial skeleton and the appendicular skeleton. The axial skeleton is the vertebrae (backbone), cranium (skull), and rib cage. There can be two regions of the skull, or chondrocranium—the neurocranium and the splanchnocranium. The neurocranium is the dorsal, or top part of the skull, that has to do with protecting the brain and sensory organs. The splanchnocranium is the ventral, or underneath part of the skull, concerned with forming the jaw and the gill arches. The powerful jaws, of course, contain the numerous teeth, which are attached by ligaments to the jaw, and upon falling out, are replaced by teeth that were developing all along behind layers of skin. The neurocranium has lots of little foramina, or perforations in it, for such things as a primitive “third eye”, protection for the lateral lines, openings from sensory organs into the cranium, and other stuff. It also has the rostrum, or snout, of the shark. The splanchnocranium has the mandibular arch, which is the jaws, as well as other support for the sides of the shark’s comparatively massive head. The axial skeleton also includes the long vertebrae down to the shark’s tail, which contains the notochord, the spinal cord, the caudal artery, and the caudal vein. The appendicular skeleton contains the assorted fins—dorsal, caudal, pelvic, and pectoral—as well as the pectoral and pelvic girdles. Attached to the pectoral girdle, which is like a big belt around the middle of the shark, are the two wing-like pectoral fins, and attached to the pelvic girdle, a smaller belt nearer the tail of the shark, are the pelvic fins. Each set of fins is attached to its girdle and supported by a notochord. The shark’s skeleton is complicated, but simpler than that of say, a human. ^{vi i}

Sharks’ fins differ according to species, and are very different from bony fish fins. Sharks that don’t dwell exclusively on the bottom have much stiffer pectoral fins than those that do. Shark fins are generally inflexible, unlike the fins of bony fishes. The shark uses its tail as the main method of movement, with the fins providing lift and buoyancy, kind of like airplane wings. The hammerhead shark doesn’t have very large pectoral fins, for example, because its weird head provides some lift for it. Dorsal fins aren’t just for decoration, either. They aid in steering efficiency and may help block water flow to the tail, increasing the result of the thrust from the tail and preserving energy. Bottom dwelling sharks have smaller dorsal fins that top dwelling sharks, because they don’t need to move as quickly. The downward sweep of the asymmetrical caudal fin, with its large dorsal lobe and small ventral lobe, also helps with lift.

Despite the light skeleton, a shark is negatively buoyant—it sinks. The shark also lacks a swim bladder, which other fish have. Although a shark must be often in motion, it isn’t true that it must be continuously in motion to stay afloat. The shark contains a liver with very light oil to help it stay afloat. Pelagic, or open-ocean sharks, which need to stay afloat more than bottom dwelling sharks, contain larger livers with lighter oils. This makes an effective buoyancy system.

The shark breathes by exchanging gases through its gills. The water taken in through its mouth passes over the gill filaments, where gas exchange takes place. The carbon dioxide is released from the blood at the gill lamellae and exits via the gill slits with the water. Sharks have between five and seven gill arches just in front of the pectoral fins. They slits are never entirely below the pectoral fins. Some sharks must swim continually to ensure that they get the oxygen they need past the filaments, but others have a special pharynx in their throats that pumps the water past the gill filaments. There is no protective covering over the gill slits, unlike with bony fish, so they are more vulnerable to injury. Many sharks, especially bottom dwelling species, also have spiracles on the dorsal side of their skulls that are kind of like extra gills, so they can ventilate while feeding slowly on the bottom. These spiracles have a special valve to keep things flowing.

Sharks’ guts are as interesting as any—if you’re into lots of greasy yellow stuff. There’s a really cool fat esophagus, which is really large considering the size of the shark, since the food is normally swallowed in big, whole pieces. The stomach can expand considerably, and follows the esophagus immediately in a caudal directed J-shape. Following the stomach, which is lined with white lobey things on the inside called rugae, is a duodenum, connected to the gall bladder and the intestines, where the bile breaks down the shark’s food. Following the duodenum is the valvular intestine, or the rest of the small intestine, which contains spiral valves to increase the surface area and absorption of the intestines. The colon is the continuation of this intestine. The rectal gland leads into the colon by means of a duct. It excretes salt to regulate the shark’s body fluids. Normally, the concentration of salt in the shark is lower than that in the sea, so it is in danger of dehydrating through osmosis. The salt excreted by the rectal gland increases the concentration of salt in the shark, in a sense decreasing the concentration of water, so that the concentration inside the shark is the same as outside, preventing any osmosis from occurring. This is called an osmoregulator. The shark has one final end to the digestive tract—the cloaca, meaning sewer. Higher organisms such as humans have different organs for the rectum, the reproductive system, and the urinary bladder, but the shark just uses the cloaca for all three.

The shark’s liver is also really cool—and REALLY HUGE!!! (In some it takes up 30% of the shark’s body weight, and it takes up practically 50% of the inside room of some sharks) The shark needs a lot of liver to store all the oils for all the energy it needs, besides the fact that the liver aids with buoyancy, as aforementioned.

Sometimes sharks have two types of muscle tissues, red and white, kind of like light and dark poultry meat. The red contains a high concentration of myoglobin that stores oxygen. The red is used frequently on long trips, and the energy produced while burning the oxygen is used for heat. White muscle makes up the majority of the muscle mass, but doesn’t store much oxygen.

The shark has a complex circulatory system, like a human’s, except with only a three-chambered heart rather than a four chambered heart, with one big artery entering the heart from the top. The three-chambered heart appears much less complex than the four-chambered from the outside. There are veins leading away from the heart and arteries leading to the heart, passing by the essential gills on the way.

The senses of the shark are very highly specialized and perfectly sharp. The neurological system is very advanced. The shark’s hearing is especially amazing--sometimes sharks can hear things from a mile away. They are especially sensitive to sounds in the range of 20-300Hz, particularly at or below 40 Hz, which is about the frequency of a struggling fish. The hole-thing above the eye, though, is not the ear---that’s the aforementioned spiracle. The outer ears are very small pore-like objects between the spiracles, and while the inner ear is very extensive, hidden entirely inside the otic capsule of the chondrocranium, the outer ear is small and almost impossible to see without a magnifying glass or hand lens. The inner ear also contains three semi-circular canals, which, as in humans, provide the primary sense of balance, besides that provided by the eye, by way of fluids and salt-like grains flowing past the canals in a huge hole called the sacculus. The nose is also a wonderful creation—blacktip sharks have been known to detect fish diluted to one part per 10 billion parts of seawater. The shark can also smell from many yards away. Its olfactory organ—or, “nose”—has two external nares, each with two openings, one lateral, an incurrent aperture, and one medial, and excurrent aperture. (Feel free to refer to the attached sketches at any time) A part of the brain called the olfactory bulbs touches the olfactory sacs, internal cavities leading out to the nares. The shark actually takes in water, passes it over some epithelium, or special sensors lining the sac-insides, and then shoots it out again for more. This water flow is regulated by a flap of skin between the lateral and medial apertures. The eye of the shark is probably not as wonderful, and of course picture quality depends on the quality of the water, but it is relatively the same as that of the human. Any of you who happen to be humans focus by changing the shape of the lens—the shark focuses like a camera, moving the lens further or closer to the retina of the eye. Just like you humans, the shark has a pupil to regulate the amount of light entering the eye. The shark has both cone cells and rod cells, so it can probably detect some color, and sees highly contrasted objects well, although it is not known how well it can see subtle details. Many sharks have a tapetum, or reflective layer, behind the retina that allows them to make the most of the little light they have. Many also have a nictitating membrane on each eye that aids to protect the eye during encounters with prey. The shark also has well-developed touch and taste—developed enough to reject things it finds distasteful. The tongue is very short, so the shark can only taste things far in its mouth. The shark also has a very interesting lateral line system, which only fish and amphibian larvae have, as far as we know. The connected lateral line canals form a long line on either side of the shark’s body, just under the skin, and are exposed to the outside water by little pores. The lateral line system is made of neuromasts, which are the ciliated sensory cells in the canals, and detects water current, so the shark can tell if something is moving the water nearby and in what direction. Another interesting feature of sharks is the ability to detect electric fields produced by the bodies of some organisms. The fields are detected by the pores of ampullae of lorenzini, which lead to the ampullae of lorenzini, which store a jelly-like solution and are attached to a sensory nerve. This aids the shark in knowing where the prey is when it’s very close and just about to bite. They can use this also to detect buried prey as the sharks go over the ocean-bottom. The pores are on the underside of the snout and are huge and clearly visible.

SHARK LIFE

Sharks have many different modes of reproduction. Sharks do not stay together for life, and only come together during mating season. The male has two claspers, which are modified pelvic fins for transmission of sperm, on its underside, near the pelvic fins, and the female has nothing but the cloaca and the pelvic fins. Sharks utilize internal fertilization. Mating gets very violent as the males will hold the females with their teeth to put them in the mating position, which is why females have skin twice as thick. Some sharks breed year round, and others migrate to a mating ground every two years or so. Sharks tend to give birth in the summer, or spring, or when the water is a tolerable temperature, not too hot and not too cold. It is thought that female sharks give off pheromones, special smells, when they are ready to mate, to let the males know they’re available. This is when it ceases to be all the same for every species. Some sharks are oviparous, and lay the fertilized eggs to hatch on their own. Some sharks are live bearing. Some live bearing sharks use placental vivipary, where the embryo is attached to the mother and receives nutrients from her. Others have the embryo attached to a yolk-sack within the uterus. If the yolk ever runs out, the embryo will eat other embryos or eat the unfertilized eggs in the oviduct that leads to the uterus tubes. Once the shark hatches or is born, it looks just like its parent and is on its own. Sometimes the mother will eat her babies. ^vii

Sharks have varying lifestyles. Many migrate vertically, and many migrate from south to north for breeding and temperature changes. Sharks also tolerate a wide range of pressures. Centroscymnus coelolepis has been found at depths of 8000 ft, while some sharks are restricted to 600 ft. Most sharks are carnivorous and feed on fairly large prey. All sharks have wonderful sensory reception and low intelligence, although the temperament varies from species to species. The sand shark (Carcharhinus plumbeus) is sluggish and “lazy” while the tiger shark has been known to actually consume people for no reason at all. Some sharks live on the bottom, some in the middle, and some are pelagic, on the top of the ocean. A shark’s lifestyle depends on the shark. ^viii

^{THE SHARK AND YOU}

It is hard to write about the shark without mentioning what it has to do with you. Despite the ideas the Jaws series inspired, sharks do not eat people, and the actions of one or two deranged individuals should not dishonor the species. There are a few more dangerous types of sharks—the tiger shark, the lemon shark, large hammerheads, and the great white. These are the ones most likely to attack without provocation. Often it seems they simply wonder what you are and taste you, like a baby does. It just so happens that you taste awful, or something, because they don’t eat you, but rather take a bite and leave. This bite, though, unfortunately results in the loss of limbs or even in fatalities. Swimmers are more vulnerable than surfers, presumably because swimmers look more like food. Actually, though, more people die from wasp stings than white shark attacks. Off of Virginia there has only been one fatal attack since 1670, and 3 non-fatal attacks. And while you think about that, why not “tasting” a shark? Your taste would be much more fatal to a shark than his would be to you. Shark meat is wonderfully boneless, the best meat being firm and flaky. The Atlantic Mako is an especially popular meat shark, because it makes lovely leaps and runs when hooked. Conservation is important, but there are many shark species that are not endangered and taste good, too! For shark fishing, make sure you have some kind of rope, hook, and pole, as well as something on your 35 to 40 ft. boat to lift the shark out of the water with. When you have gutted your shark, make sure to get all the blood out, or the meat will turn brown and taste very dry. You can do it just like you would to any other large fish, although instead of scraping off scales, you skin it—kind of like hunting and fishing together. You can soak your filets in an acidic solution like lemon juice to further remove any yuckiness. When you preserve it, double-wrap your shark and use un-iodized salt, like kosher salt—otherwise the shark will spoil and turn black. Glaze the inside of any crock you use, preferably plastic, after soaking the shark in a salt brine to make absolutely sure you got all the blood out. After washing and draining, you can put the shark in the crock layered with salt, covering the last layer of shark with about an inch of salt. Shark meat can make anything from fin soup to teriyaki! Just make sure you use the whole shark and don’t waste these magnificent creatures! ^ix

THE DOGFISH SHARK

Our shark is a spiny dogfish, Squalus acanthias, from the family squalidae in the suborder squaloidei in the order sqauliformes. This order contains 7 families and 113 species like dogfish, cookie cutter sharks, spurdogs, rough sharks, etc. The sharks in this order range in size from less than 8 in. to over 20 ft. They all reproduce live bearing without placenta, as far as we know.

The spiny dogfish shark has a gray/brown dorsal surface dotted laterally with white spots that fade as the dogfish gets older. It has no anal fin, almost perfectly equilateral pectoral fins, a rear dorsal fin behind the pelvic fins, and a caudal fin without a ridge or chip out of it. The dogfish has large, beautiful eyes and a kind of flat head. Like the smooth dogfish, it has two rows of low, grinding teeth, but also a row of small, sharp teeth. It also has a spine in front of its dorsal fins which it can us in defense by doubling up like a bow and striking the mildly venomous spine into its attacker.

The spiny dogfish is migratory, found primarily north of Cape Cod in the summer and south in the winter. It lives at almost any depth and prefers highly saturated sea-water to brackish freshwater. The deepest known depth of a spiny dogfish was 2950 ft.

The dogfish is a social shark and travels in groups segregated by size and sex. Medium sized males travel with medium sized males, and big females with big females, and so on. Only the immature dogfish travel in mixed sex groups, although still sticking with sharks their own sizes. The dogfish got its English name from the way these sharks travel in packs and attack the small fish in their way.

The spiny dogfish eats crustaceans like the smooth dogfish, but feeds primarily on small fish such as herring. It often tears fishing nets to get what’s inside and is a pest to commercial fishing.

The spiny dogfish’s age has been found by growth zones on its spine, and dogfish can live between 25 to 30 or even more years. The dogfish has the longest gestation period of any known vertebrae—almost two years! The spiny dogfish also grows up very slowly. The Peter Pan of sharks, the spiny dogfish female isn’t mature until at least 12 years of age! The dogfish’s size upon reaching maturity varies from climate to climate. It grows between 1 ½ to 3 feet in length, the largest around 4 ft.

The spiny dogfish is an aggressive little shark, the young pups attacking fish two or three times their sizes. It is no real harm to man, although the spines can prove dangerous upon handling of this shark, and no dogfish shark that we know of has ever killed a human being.

Although the spiny dogfish is considered a bore to sportsfishermen and a pest to commercial fishermen, its flesh is flaky and firm like haddock and well-loved in Europe. If you eat fish and chips, the fish is very likely the spiny dogfish. x

And that’s it! We hope you enjoyed our whirlwind tour into the life of a shark. The typist has especially come to love the dogfish shark, and hopes that you did, too, or at least came to enjoy the magnificent sharks the Lord has placed on this planet! Googling “shark” will give you lots of results—try it some time, dissect a shark, write a report, and tell us if you don’t discover something amazing!

Leaves of Impermanence,

Colors of Time: Seasonal Imagery in Selected Nara Poetry

As the leaves outside the dorm room finally begin to fall, hailing the end of this summer inferno without air conditioning, first year students everywhere glory in the coming of autumn. Much like these first year students, the Japanese poets of the Nara period give a special significance to the seasons and their transitions. In poetry, yearly times of change illustrate the stages of human life in many facets, altering the literary view of knowledge, growth, and beauty. In the poetry of Kakinomo no Hitomaro and his predecessor, seasons explain the phases of human life, investigate the transience of existence, and extend that discussion of transience to the political realm, finally providing a means to compare the individual’s relationship to society and time.

The Man’yôshü poets used seasons to expound on a reasonably wide range of topics but the most blatantly obvious imagery pertains to a discourse on the phases of human life. Every life begins in the youth of spring, continues strongly through the peak years of summer, and begins to fade away as the autumn brings winter in “an aesthetic of impermanence.” (65) In one of the earliest poems in the Man’yôshü the poet Lady Nukata answers the question as to which of the seasons, spring or fall, she prefers. Nukata admits that even she, a great noblelady, must “leave the green [leaves] with longing, and that is [her] only regret.” (66, lines 8-9) In other words, we all pass into phases, such as death, where we must leave behind former treasures, former ‘green leaves.’ The question really addresses Nukata’s degree of willingness to release her hold on the impermanent.

For an answer to the comparison between spring and autumn, Nukata first treats the greatness and the shortcomings of spring: the seasons of youth or strength in our lives. When we enter the spring seasons of life we enjoy many blessings, many ‘green leaves,’ but “the grass is so deep that nothing can be seen.” (66, line 4) If spring is youth or strength, Lady Nukata’s ‘deep grass’ can refer to the greatness of the opportunities and the freshness of the distractions before us that keep us from understanding and plucking substance out of our lives. The hindrance of the ‘deep grass’ finally moves Lady Nukata to choose the autumn hills in the last line of the poem. She writes that, in contrast to spring, the autumn season brings wisdom, the ability to “see the tree leaves/And pick the yellow ones with wonder.” (66, lines 9-10) As she inevitably leaves one phase of her physical lifespan to enter the door of another, she recognizes a need to understand and gather from each phase she enters.

While for Lady Nukata spring and autumn seasons point to evanescent phases, Kakinomoto no Hitomaro uses the seasons in his Yoshino praise poems to express power and control. The Empress Jitô has symbolically identified herself with her predecessors by visiting the Yoshino palace, and as she looks out from it onto the land, Hitomaro writes her a glory poem. Overall, it speaks using contrasting pairs to establish her legitimate reign over all areas of life, from the mountains to the rivers. The seasonal imagery arises as “the mountain gods present their offerings/bringing her blossoms in the spring/and yellow leaves when autumn comes…”(73, lines 7-9) This section serves a two-fold purpose. On one level, these can be read as praises of the Empress’s person. A woman gifted with ‘blossoms in the spring’ is physically blessed with the power and beauty of youth. Similarly, a woman who has picked the yellow leaves of autumn has gathered other features such as grace and wisdom. A person possessing both characteristics of spring and autumn makes a good ruler; she has everything needed to qualify her. Another purpose of these symbols is the element of homage. The mountain gods relinquish the spring and the autumn to Jitô. She controls both ends of the spectrum, from spring to fall, her power encompassing not only the extremes of time but also both sides of nature’s character. In this way, the seasons give insight into her reign.

The seasons come into play in a more intriguing way in Hitomaro’s poetry when it becomes difficult to reconcile the fragility of humanity with the god-like power assigned to human political leaders and governments. In his poems on Prince Karu’s hunting forays Hitomaro almost manages to move beyond the political praise. When Hitomaro compares “our lord who passed away” to “the autumn leaves” (75, line 3) he uses an incredibly commonplace comparison without elaboration or discussion on the emperor’s divine leaving, essentially saying that just like everyone else and the leaves, the emperor died. The near bluntness of this statement, placing the bygone emperor on a transient plane, not only illuminates the passing nature of political governments themselves but also brings the emperor down to the rest of humanity.

It can be argued that this reading of the text forces into Hitomaro’s poetry an egalitarian worldview that should not be assumed given the historical context. Point taken--however, in the next tanka Hitomaro continues, “the blaze can be seen rising…the moon has set,” (75, second poem) indicating that though the emperor has died there is a new power. Hitomaro supposedly writes the poem legitimizing the authority of the new prince, Karu, (74) and the sun rising represents this boy’s ascent to the throne. However, the sun will set again. The summer reign of the “peer of the sun” (line 6 of the first short poem, 75) can end in autumn leaves. There is always a higher power, says Hitomaro. He ends his poem series with a short tanka emphasizing the eternality of the dynasty by linking Karu to his predecessor using mixed tenses. “The time IS COMING,” Hitomaro writes, “when the prince who WAS the pier of the sun…/set out to hunt.” (emphasis mine, last tanka) This time confusion allows the life of the past emperor to describe what Karu will do in the future (75). Despite the projected confidence in the ruling political power, however, there is always the knowledge that the previous sun did set. There will always be a cycle. The government, centralized around one person, may establish a near-permanence in its god-like dynasty, but times will always continue to change as people pass on. The double-nature of the short poems on the hunting trip works because of the slightest seasonal symbolism. Remove the images of the autumn leaves and the sun, and you have a praise poem completely lacking any other interior meaning.

Hitomaro continued to milk the seasons of political uses in his Poems On Passing the Ruined Capital of Ömi, this time extending the idea of human transience from emperors to apply to societies. This time the complication arises in acknowledging a capital that has fallen out of favor. The Ömi capital had once housed the emperor Tenchi, held in high esteem by the ruling Yamato court, but on the other hand it had housed the enemies of the current regime. (79) The reconciliation or appeasement of the Ömi court spirits occurs when Hitomaro recognizes the beauty and power of the court throughout the beginning of the poem and then uses seasonal imagery to show that the political transitions were natural and inevitable.

Hitomaro acknowledges then that the “divine sovereign,” Tenchi, (line 13) chose to rule at Ömi, but then moves on from his description of the rocky, “barbarous” landscape (lines 11-12) to speak of an appropriate replacement. Spring always ushers in the new, and in lines 16-17 we read, “Here were his glorious halls/Now all is overgrown by the spring grass/And clouded by the haze of the spring sun.”(80) The new ‘sun,’ and the new emperor, cloud over the glory of the old regime. The spring has come, conquering the cold environment, and the new courtiers and new actions of the court have overgrown and overtaken the old. The spring transition emphasizes not merely the transience of the old regime, but also the greatness of the new. At the same time, however, Hitomaro continues to say in the final line that “we are filled with sadness,” illuminating his nostalgia of the passing phases that society must inevitably leave behind. Only the use of the seasons can express the necessity of forward motion while touching so tenderly and naturally on that which came before. Entire capitals, like emperors and humans, fade into the past to give way to a greater future.

Court society, however transient, held a bond over Hitomaro that he recognized. His poetry did not necessarily come voluntarily; the government commissioned him to write praise poems and undoubtedly kept him separated from his family. The seasons in his Poems on Parting With His Wife At Iwami illustrate the special human conflict with time and society’s consuming demands by fleshing out the speaker’s internal struggle with his desire for his beloved and his timed duty to court.

The speaker speaks of his time with the girl in summer terms. She felt to him like a warm sea, and Hitomaro puts forth many beach and seaweed metaphors in the first lines to illustrate the pleasure the lovers experience together. (81-82) The speaker’s time with his beloved is cut short, however, by his requirements to the court and ultimately to society. He thinks of her “wilting with sorrow/like the summer grass” (82, line 13). The heat of their love and the passion they feel in separating themselves leaves the girl wilted. As time moves the seasons on, so time has cut short their moments together in the name of the court. The girl must move on from the summer they both feel inside as the speaker leaves her “like the dew and the frost.” (line 7) The separation quickly creates a winter. There is limited contact from afar in Hitomaro’s day, and the two feel keenly the cold cruelty that time has inflicted on them. The memories together become like dew and frost, like cold transparencies, as the summer grass wilts.

The speaker is separated from his girl by autumn, the parting that brings the pair from summer together to winter apart. “Through the yellow leaves as they scatter/I cannot see my girl waving her sleeves” (83, 12 line on page) Yellow leaves are autumn’s messangers, the servants and soldiers of time that take us away into the future and obscure our connections with the past and present. They are the driftings and partings in life that interrupt as the winds of time pass. They are the commitments that take the speaker away and fly between the lovers. The speaker must move forward, away from the summers he spent with his girl, on to the winter of court life, through the parting of autumn.

However, even as the yellow leaves force the speaker from summer to winter, they themselves are also passing away on the wind. “Yellow leaves, falling on the autumn hill/ Stop scattering for just a while/So I may see the village of my girl,” requests Hitomaro. (84) The scattering need not continue forever. The wind may die down. The changing of the seasons continues unchangeably, and by using the seasons to describe his departure Hitomaro offers hope that the speaker may return. He poignantly requests in this last stanza that he be allowed to rejoin or at least see his beloved, in the hope that the court, like weather, is not permanent. Interestingly enough, Hitomaro uses similar yellow-leaf language to address the death of the woman in a later poem (84). Using the seasons always indicates that if a current situation is unsatisfactory, it may alter itself over time. Perhaps even death possesses a seasonal quality, hints Hitomaro’s usage.

 Seasons illustrate human transience. Hitomaro took this idea and extended it in his poetry, analyzing this transience in respect to the emperors he praised to remind his readers of a humanity that came hand in hand with their ‘godhood.’ He used the seasons to praise his clients, but also showed that their position as humans came with a fading quality. This fading quality does not limit itself to the human individual, he pointed out, but to entire societies. The individual has hope, and indeed, value because the society above him is transient. When the master limps, the servant has more equal footing. While society may work as an agent of time to move us forward, we all have the hope that in the even further future we may stand on our own terms again. Just as autumn follows summer, spring follows winter, and our lives are most valuable when we can take the most insight and internal beauty out of the time we have been given. Hope, then, is the knowledge that we may pick the autumn leaves that keep us from our dreams and discover that beyond them there may be a greener field.

How The Ethan Couch Case is About The Advantages of Wealth, Not Race

The Ethan Couch case is about the advantages of wealth, not race, and if we want to overcome the prejudices against the impoverished black community as a whole, we need to understand that.

If you just think about it with me you'll see why. Take this scenario: a well-dressed, wealthy good-looking young black man (who probably gets straight As and comes from a "good" family) approaches you late at night on the street, dressed in a button-down shirt and tie or at the very least a polo and khakis, and he asks you the time in "perfect" polite English. Now, a dirty-looking white guy with his pants hanging down around his knees, a du-rag wrapped around his head, long-hair and a cigarette in his hands slouches towards you asking you the same question in slurred, cursing speech. Who makes you uncomfortable?

Most people, regardless of race, answer the white guy, if they really think about it. Most importantly, MOST PREJUDICED WHITE PEOPLE today would answer the white guy JUST because of the way he's dressed. If you don't believe me, ask your slightly-racist white friends, if you have any, and I bet you $50 the majority of them will answer the pants-down guy.

There's nothing wrong with wearing a du-rag, wearing your pants kind of down, or having long hair as a male; smoking's legal if he's over 18, and lots of nice people curse (like me, dammit). Middle and upper-class Americans just have cultural stigmas against those things. Now, my pants-down-white guy is wearing a stereotype that's unfortunately been applied to black people because inequalities in American history put a disproportionate number of black people in lower socio-economic tiers. But today's prejudices against black youth really are related to Povertenza, not "black-enza."

Now put the well-dressed black youth and the pants-down white guy in court, and you see what I'm getting at. I'm not saying that, all other things equal, a well-dressed educated black man and a well-dressed educated white man will have the same outcomes, because honestly, those cases don't comprise the majority of the unjust sentencing stories. Look back at the news over this year: in almost every major case of unjust sentencing against a black person where the black person LOST, the black person came from a lower socio-economic tier. Every time the black person comes from a higher socio-economic tier (like when the stupid white policeman tried to arrest a black Harvard professor entering his own house), there's a better outcome (the stupid white policeman got in trouble). All other things equal, class is a much more damning factor because we still judge by appearances. We've all heard in school that racism's bad, and that's incredibly important. But no one goes around teaching the kids about classism, which is arguably a deeper financial wound against the black community. Instead, we've got wealthy and middle-class folks white AND black telling their kids that poor black people just didn't work hard enough, rather than trying to give a kid a hand.

Ethan Couch got off because of affluenza. No one on the defense said he should get off because he's white. I think that's very telling about where our court system's come from, and how far our society still has to go before it finds true equality.

Oh, and if you asked your slightly-racist white friends about this scenario, you owe me $50. My paypal is petrepan at gmail. (Help me overcome my new-found povertenza)

Heart Health Benefits of Red Wine--and Local Wine-Pairing Program

Tomorrow, on Saturday, July 27th, Charlottesvillians and food enthusiasts of Albemarle county will gather at Ducard Vineyards for a continuation of the Food and Wine Pairing Program.

"These will be small group, seated tastings in the new barrel room where we'll have in-depth tastings of our current releases," said a Ducard representative in an e-mail to Examiner.

The menu, according to Ducard's website, will showcase various summer-vacation-style items including crabcakes, cheese, bruschetta, sausage, and chocolates.

Visitors will also try vintage wines straight from the barrel in the 60 degree Fahrenheit cellar, said the Ducard representative--a welcome escape from the sweltering summer vacation heat.

Alcohol produces tissue-damaging ketones that promote oxidation and free radical production, primarily in the liver; Charlottesville's red wine, however, may promote heart and vein health, according to a June 27 study in Autonomic Neuroscience this year.

Scientists have long suspected that antioxidants called polyphenols in red wine and grape juice may prevent or treat hypertension, or high blood pressure, but they hadn't fully studied the effects on cardiac autonomic function, according to the June 27 study. This means they didn't know how red wine affected the heart's control of its beat.

So how does red wine affect your heartbeat? Read more here! http://exm.nr/15RiAvE

Nine tulip flavors for salads & appetizers from Charlottesville's organic tulips

Tulips of different flavors offer different tastes, which gives aspiring appetizer-artists and salad-creators a number of options. Before buying tulips, it may help to know which flavors offer which colors, so here Charlottesville's Nutrition Examiner presents a list of nine flower-flavors for Charlottesville's explorative organic eaters.
 

Some thoughts before consuming petals: EcoTulips Vice President Keriann S. Koeman recommends thorough washing to remove pollen, which will give a strong peppery taste that burns the back of the throat. She implores consumers to avoid non-organic tulips for consumption: the powerful pesticides used on normally non-food flowers may be harmful to human health.

Nutritively, there's little information on the value of these petals, but certain colors in vegetation often indicate the presence of certain nutrients, says Koeman. The red and orange, for example, usually indicates the presence of beta-carotene, a substance that helps vitamin A improve skin, eye, and immune system health. While there aren't many documented tulip consumption allergies, data mined from dictionaries and encyclopedias indicates that some people do have dermatitis reactions in response to petal consumption. Animals who have eaten the bulb and the petals have died because of the anti-nutritives in the bulb, so it's important to look at preparation warnings before bulb consumption; Examiner.com offers several tulip cooking ideas.

5 ways for Charlottesvillians to eat organic tulips

With spring picking season in full-swing for the nation's only certified organic tulip supplier, a Charlottesville flower-expert opened up for Examiner about five edible possibilities for Holland's favorite bloom.

Keriann S. Koeman started Charlottesville's local EcoTulips with her Dutch husband in 2009 with an emphasis on pesticide-free, farmer-friendly tulip growth. Like Charlottesville itself, the company's success grew out of international influence, and influence from local farming backgrounds.

Now, EcoTulips sells tulips at $1 per stem during picking season, and online for a bit more for the rest of the year. The company recently branched out to sell USDA-certified Dahlias, and they run a partnership program for schools, churches, and nonprofits interested in using tulips for fundraising.

While most customers arrive to the field to see and maybe smell the flowers, Koeman offered several tips for taste. Nearly--nearly is the key word here--all the parts of a tulip are edible and like lettuce or other greens, relatively healthy.

Read on for five edible tulip tips.

Ch-ch-ch-chia Charlottesville: Where to buy chia's top 3 health benefits via Examiner.com

  Chia seeds, once popular as the 1980's green-haired clay pet, have made a comeback as a health-food throughout the nation--and Charlottesville--with rumors of weight loss, high-protein energy, and even diabetic help.

Chia seeds first became popular with the Mayans, who drank them, ground them into flour, and mixed them as oils as early as 3500 BC; the later Aztecs believed one tablespoon could sustain a warrior for 24 hours, and they treated chia as a sign of strength. When the Aztecs conquered other peoples, they demonstrated that strength by demanding chia seeds as tribute, symbolically as well as literally "sapping the strength" from their enemies.

Today's chia-consumers may see chia differently--more as a food for "back-to-nature" health-hippies than violent warrior's fare--but the nutritional requirements remain the same. To help health-conscious readers track down the elusive black-and-white marbled seeds, Charlottesville's Nutrition Examiner contacted grocery stores across Charlottesville to discover who's stocking. When possible, Examiner dug up prices to help Charlottesville's health-nuts compare cost. Charlottesville-area chia shopping grounds include:

• Kroger on Barrack's Road (1159 Emmet St N) stocks three or four varieties ranging around $9.99 for a small bag.
• Kroger at 1980 Rio Hill Center stocks a 16 oz box for $9.49 and a 1 lb bag $21.99.
• Whole Foods on 1797 Hydraulic Rd stocks several different brands between $6.99 and $17.99. Organic varieties begin with a Whole Foods Brand 15 oz bag at $18.99, Nutiva brand $16.99 for 12 oz bag, and Navitas $17.99 for 16 oz bag. Conventional brands stocked include Spectrum, at $12.99 for a 12 oz bag, and The Chia Company on sale through end of April 2013 with $6.99 for a 5 oz bag, 17 oz bags for $16.99, 12 oz bags for $15.99, and 35 oz tubs for $26.99.

Are the health benefits worth the costs? Our Charlottesville Nutrition Examiner checked current scientific research to find out. Click forward for the top 3 scientifically-proven health benefits of chia.
