Greenland Sharks apparently taste like urine.
Although they are an Icelandic delicacy.
They are poisonous to eat without proper fermentation and preparation – on account of the large amounts of urea and ammonia in their blood. Anthony Bourdain said Greenland Shark is the single most disgusting thing he ever tasted.
Fermented Greenland Shark
There’s literally an Inuit Legend (An Indigenous People in Northern Canada) which says the Greenland Shark originates from a urine-soaked cloth that was thrown in the ocean by an old woman – resulting in Skalugsuak.
BUT they live for hundreds of years, so they must be doing something right!
