Greenland Shark Somniosus microcephalus

The sluggish Greenland shark has a heavy, cylindrical body that is usually brown or gray. It has a short, rounded snout and two equal-sized dorsal fins. As well as feeding on a variety of live prey, including fish, sea birds, and seals, the Greenland shark is also a scavenger, often eating dead cetaceans and drowned land animals, such as reindeer. It is often caught by hook-and-line at ice holes while it hunts seals, but the Greenland shark's flesh is poisonous and must be boiled several times before it becomes edible.
