The Greenland Shark Essay -- science

The Greenland sharksharks live in almost every region of the oceans, from coastal environments to deep-sea home grounds. They as well live in the warm body of waters of the tropics to the cold frigid waters of the polar region. The Greenland chisel, also cognize as somniousus Microcephalus, lives in the dispirited, cold waters of the North Atlantic (I 65). The Greenland shark belongs to the order Squaliforms, more usually known as dogfish sharks. in that location are 70 species in this order, which includes the spied sharks, spiny dogfish, Sleeper sharks and lantern fish (I 50). Greenland Shark Classification Kingdom Anamalia Phylum Cordates (possessing a notochord) Sub Phylum Vertebrates (possessing a back bone) A-one Class Gnathostomata (jawed vertebrates) Class Chondrichthyes (cartilaginous skeleton) Subclass Elasmobranchas (ribbon like gills) Super aim Selachii or Selachimopha (shark shaped) Order Sqauliforms Family Sqaulidea Species somniousus Microcephalus (I 185) Th e sharks habitat largely depends on the water temperature this allows its habitat that ranges from the Polar latitudes to the North ocean in the east and the St. Lawrence River in the West. The Greenland shark has also wonders south as far as the waters off Cape Hatteras and has also been tack together 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 depths. In the winter months the Greenland sharks can be found at the surface and at the edges of ice 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 just 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 diet of a Greenland will eat almost an ything that it will come across. With its slow liquified body plan, it includes bottom living shellfish, yet it also hunts seals, porpoises and other tiny whales and sea birds at the surface in its diet (I 65). These sharks also have many kinds of fish, such as capelin, char, herring, halibut, lumpfish and charge salmon. There has even been fast swimming fish found with its tail bitten off wrong ... ...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 get those fast swimming fish to the oral side of the shark. With out these parasites it is feasible that the sharks could not catch as many fish as it does, collect to its slow speed. On top of the parasites on its eyes, the Greenland shark also has insalubrious mannequin. To get rid of the poison n order to eat it, the flesh must be boiled and dried several times (II 63). If the centerfield is not prepared corre ctly, it can cause, nausea, vomiting, diarrhea, and abdominal pain, tingling and burning hotshot of tongue, throat and esophagus. It can also cause muscular cramps, respiratory distress, comatoseness and death (III Vol 25, 905). This shark may not kill you when its alive, but you have to careful when its dead. References 1.
