sleeper shark
Slow abyssal hunter
Sleeper sharks are a family of large, slow-moving sharks found in cold, deep waters.
Named for their sluggish behavior, they drift through arctic and subarctic seas, sometimes at extreme depths.
The Greenland shark, the most famous species, can live for centuries—among the longest-lived vertebrates known.
Despite their torpid appearance, sleeper sharks are effective predators.
