Blind shark
This shark has its eyes eaten by a parasite, gross.
The Greenland shark (Somniosus microcephalus), also known as the gurry shark, or grey shark, or by the Kalaallisut name eqalussuaq, is a large shark of the family Somniosidae ("sleeper sharks"), closely related to the Pacific and southern sleeper sharks.[2] The distribution of this species is mostly restricted to the waters of the North Atlantic Ocean and Arctic Ocean.
It has the longest known lifespan of all vertebrate species (392 ± 120 years), and is among the largest extant species of shark. As an adaptation to living at depth,[3] it has a high concentration of trimethylamine N-oxide in its tissues, which causes the meat to be toxic.[4] Greenland shark flesh treated to reduce toxin levels is eaten in Iceland as a delicacy known as kæstur hákarl.[5]
