Can you eat a Pacific sleeper shark?

It’s difficult to study animals that live such a reclusive lifestyle because it’s hard to reach them at such deep depths. Furthermore, people don’t eat or use these sharks, so there isn’t much economic incentive to learn more about them, as with school sharks or porbeagle sharks.

Pacific sleeper shark. The Pacific sleeper shark (Somniosus pacificus) is a sleeper shark of the family Somniosidae, found in the North Pacific on continental shelves and slopes in Arctic and temperate waters between latitudes 70°N and 22°N, from the surface to 2,000 metres (6,600 ft) deep.

How big was the sleeper shark filmed?

In 1989, an enormous Pacific sleeper shark was attracted to a bait in deep water outside Tokyo Bay, Japan, and filmed. The shark was estimated by Eugenie Clark to be about 7 m (23 ft) long. Due to living in frigid depths, the sleeper shark’s liver oil does not contain squalene, which would solidify into a dense, nonbuoyant mass.

How deep can a sleeper shark swim?

The Pacific Sleeper Shark is found almost all around the planet, although they prefer to swim in deeper or colder waters. Depths from the surface to more than 2000 meters or 6,500 feet deep are common (that’s more than a full mile under water!).

How can you tell the age of a Pacific sleeper shark?

Determining the age of sharks is problematic. Bony fish can be aged by counting the annual rings on a bone in the ear called an otolith; most sharks do not have any bones and no shark has an otolith. REPRODUCTION: There is little information on Pacific sleeper shark reproduction.
