Sleeper sharks

Sleeper sharks are found worldwide, from the Arctic Ocean to the Antarctic Ocean. However, they are also found in tropical and temperate waters. The sizes of the species can vary greatly. The Greenland sharks, for example, can reach a length of well over 6m and are with hundreds of years one of the most long-lived species in the animal kingdom. All members of this family show a ovoviviparous style of reproduction (aplacental viviparity).
