The Greenland Shark Essay -- science

The Greenland SharkSharks live in more or less every part of the oceans, from coastal environments to complex-sea home grounds. They to a fault live in the warm amniotic fluid of the tropics to the cold frigid waters of the frigid region. The Greenland shark, too known as somniousus Microcephalus, lives in the dark, cold waters of the spousal relationship Atlantic (I 65). The Greenland shark belongs to the society Squaliforms, more usually known as dog tip sharks. There argon 70 species in this order, which includes the spied sharks, spiny dogfish, tie-up sharks and lantern fish (I 50). Greenland Shark Classification Kingdom Anamalia Phylum Cordates (possessing a notochord) Sub Phylum Vertebrates (possessing a endorse bone) Super Class Gnathostomata (jawed vertebrates) Class Chondrichthyes (cartilaginous skeleton) Subclass Elasmobranchas (ribbon manage gills) Super Order Selachii or Selachimopha (shark shaped) Order Sqauliforms Family Sqaulidea Species somniousus Microcepha lus (I 185) The sharks habitat largely depends on the water temperature this allows its habitat that ranges from the frozen latitudes to the North Sea in the east and the St. Lawrence River in the West. The Greenland shark has also wonders south as far as the waters off blanket Hatteras and has also been found in the Gulf of Maine. The shark usually lives in cool water ranging from 2-7deg Celsius (II 63). However the sharks has also been found in the waters in the Artic Circle. (I 65) Typically the Greenland sharks live at extreme sagacitys. In the winter months the Greenland sharks can be found at the surface and at the edges of fruitcake burgs and glaciers. The sharks will also enter fjords during these months. However in the warmer months of summer, the sharks dives back to depths and lives at an average depth of 100-400 fathoms and has been caught in water as deep as 600 fathoms (II 63). Depending on season and water temperature, the sharks habitat moves. The nourishment of a Greenland will eat almost anything that it will sum up across. With its slow swimming body plan, it includes bottom living shellfish, but it also hunts seals, porpoises and other small whales and sea birds at the surface in its diet (I 65). These sharks also eats many kinds of fish, such as capelin, char, herring, halibut, lumpfish and scour salmon. There has even been fast swimming fish found with its bottomland bitten off in gradient ... ...heir vision is not needed at that depth in the dark water (I 77). These parasites might actually help the sharks. These parasites are biolumiscent and they might attract those fast swimming fish to the oral side of the shark. With out these parasites it is possible that the sharks could not catch as many fish as it does, due to its slow speed. On top of the parasites on its eyes, the Greenland shark also has poisonous flesh. To get rid of the poison n order to eat it, the flesh must be boiled and dried several(prenominal) times (II 63). If the meat is not prepared correctly, it can cause, nausea, vomiting, diarrhea, and abdominal pain, shudder and burning sensation of tongue, throat and esophagus. It can also cause tidy cramps, respiratory distress, coma and death (III Vol 25, 905). This shark may not eat you when its alive, but you have to careful when its dead. References 1.
