Greenland Shark The Greenland shark, Somniosus microcephalus, also known as the sleeper shark, gurry shark, ground shark, grey shark, or by the Inuit Eqalussuaq, is a large shark native to the waters of the North Atlantic Ocean around Greenland and Iceland. These sharks live further north than any other species. They are closely related to the Pacific sleeper shark. The size of the Greenland shark is impressive; it is so large that its record is comparable to (and may exceed) that of the great white shark. Greenland Shark This shark frequently has a relationship with a parasitic copepod, Ommatokoita elongata, that attaches itself to the cornea of the eye and feeds on the shark's corneal tissue; the resulting scar tissue leads to partial blindness of the shark. However, this does not occur in all Greenland sharks.[3] Also, studies show the Greenland shark could probably detect light from darkness. The copepod is a whitish-yellow creature that was said to be bioluminescent, but this ...

World's Biggest Sharks The whale shark is a the biggest shark and the biggest fish. It is NOT a whale. It has a huge mouth which can be up to 4 feet (1.4 m) wide. Its mouth is at the very front of its head (not on the underside of the head like in most sharks). It has a wide, flat head, a rounded snout, small eyes, 5 very large gill slits, 2 dorsal fins (on its back) and 2 pectoral fins (on its sides).

The whale shark has distinctive light-yellow markings (random stripes and dots) on its very thick dark gray skin. Its skin is up to 4 inches (10 cm) thick. There are three prominent ridges running along each side of the shark's body. This enormous shark is a filter feeder and sieves enormous amounts of plankton to eat through its gills as it swims. The whale shark is up to 46 fee...
