Hákarl
Greenland sharks or basking sharks of the family Somniosidae are hunted for food in Iceland. The shark carcass is traditionally fermented in a shallow pit, with stones placed on top of the shark, allowing poisonous internal fluids, like urea and trimethylamine oxide, to be pressed and drained out of the body. The meat is then cured for several months, rendering it safe for human consumption.[4]
