Sleeper Sharks [Somniosidae]

Description

Sleeper Sharks, family Somniosidae, are named for their slow-moving nature and tendency to 'sleep' on the ocean floor. They have small eyes, large livers for buoyancy, and are found in deep waters of both polar and tropical regions. This family includes the Greenland shark, notable for its extreme longevity. Sleeper sharks feed on a wide range of prey, including fish, cephalopods, and even marine mammals.
