The Greenland shark (Somniosus microcephalus) is a saltwater fish of the family Somniosidae that grows up to 427 cm.
Description
The Greenland shark is a giant, slow-living deep-sea shark from the cold waters of the northern Atlantic and Arctic oceans. The species grows to about 430 cm and is among the longest-lived vertebrates in the world; specimens may reach hundreds of years old. It has a bulky, grey-brown body, small eyes and hunts slowly for fish, seals and carrion. Its flesh contains high concentrations of the toxin trimethylamine oxide; eaten fresh it causes poisoning ('shark drunkenness') and it may only be eaten after lengthy fermentation. The IUCN assesses the species as Vulnerable (VU).
