Greenland Shark

The Greenland shark is a large, slow-moving shark of cold northern waters, with a heavy body, small eyes and rounded snout. It feeds on fish and other animal material and may scavenge. Deep and cold habitats make much of its life difficult to observe directly. Research has revealed unusually slow growth and great longevity, though precise ages require careful estimation. Individuals use different depths and can occur closer to the surface in cold conditions. Its subdued appearance contrasts with the more active-looking forms of many coastal sharks.
