Template:Sharksportal The Pacific sleeper shark, Somniosus pacificus, is a sleeper shark of the family Dalatiidae, found circumglobally on continental shelves and slopes in temperate waters between latitudes 70° N and 47° S, from the surface to 2,000 m. Its length is up to 4.4 m, although FishBase accepts that it could possibly reach 7 m.
The Pacific sleeper shark feeds on bottom animals such as fishes, octopi, squids, crabs and tritons, harbor seals and carrion. The flesh contains a type of toxin which, when eaten, produces symptoms of drunkenness. It is one of two creatures (along with the sperm whale) that feed on giant squid and colossal squid, as research on the stomach contents of this shark has shown. Since the 7 m (23 ft) shark might have problems devouring a 12 to 14 m (39 to 46 ft) squid it is believed that the shark may feed on squid carcasses rather than live squid.
Reproduction is ovoviviparous, with 300 pups in a litter. Length at birth about 42 cm or less.
