About Sleeper

See: Gobies The Pacific sleeper shark (Somniosus pacificus) is a shark of the family Somniosidae, the sleeper sharks. While primarily associated with temperate and subarctic waters of the Northern Pacific Ocean, it has been documented in the tropical Pacific and Antarctic Ocean as well. Reaching lengths of 4.4m(14 ft), it is one of the world's largest predatory sharks. It is highly adapted to the extremes temperature and pressures of the deep-sea, including specialized liver oils and high concentrations of urea and trimethylamine oxide for survival. The sleeper shark has a sluggish reputation, but is also a versatile hunter and scavenger that migrates vertically. Due to its slow growth and vulnerability to fishing bycatch, it is currently classified as Near Threatened by the International Union for Conservation of Nature (IUCN). Description The average mature size of this species is 3.65 m (12.0 ft) and 318–363 kg (701–800 lb). The largest Pacific sleeper shark verified in size measured 4.4 m (14 ft) long and weighed 888 kg (1,958 lb), although it could possibly reach 7 m (23 ft) or more; an enormous Pacific sleeper shark was attracted to a bait in deep water outside Tokyo Bay, Japan, and...
