usually in deep water. The largest recorded specimen was a 4.7-meter-long
Sixgill Shark. These sharks feed primarily on fish, but also eat crustaceans
and sometimes carrion. They may become aggressive when provoked, but
are otherwise harmless and tend to be sluggish. These ovoviviparous
sharks bear large litters (up to 108 pups in the Sixgill). Four species
are recognized in this family; two occur in Puget Sound. They are infrequently
encountered.
