Description

The bluntnose sixgill shark is a large, heavily built deep-sea shark of the family Hexanchidae reaching about 600 cm. Unlike most sharks it has six gill slits and only a single dorsal fin set far back. The body is brown to grey with a pale side stripe and white fin edges; living animals have fluorescent green eyes. The species occurs circumglobally and patchily on the outer slope, seamounts and mid-ocean ridges, usually between 180 and 1100 m. It makes vertical migrations: resting near the bottom by day and rising at night to hunt fish, sharks, crustaceans and carrion. Large individuals even take seals and other marine mammals.
