Somniosidae is a family of sharks in the order Squaliformes, commonly known as sleeper sharks.[1]

Hákarl
In Iceland, the sharks are hunted for food. They let them rot for months to eliminate the poisonous anti-freeze these sharks have to survive in the cold temperatures they live in. They are then safe to eat. [2] These are known as Hákarl. These are a poorly studied type of deep-sea shark.[3]
Location
Somniosidae can be found in the following areas:
- Arctic to subantarctic waters
- all oceans
- shelves in cold waters
- continental and slopes
- temperate and tropical waters[4]
Feeding
Sleeper sharks may feed on Colossal squid.
