This stocky shark is often included in studies on whether or not sharks play. That is because several observers have reported seeing porbeagles in groups of up to 20 individuals manipulating and tossing about floating objects, including lumber and seaweed. They seem to engage in such activity for no apparent reason other than to pass the time.
Feeding Habits — The porbeagle shark mainly feeds on schooling fish, such as mackerel, herring, cod, hake, lancetfish, redfish and haddock. It will also consume shellfish, smaller sharks (e.g., some dogfish species) and squid. Side projections on the teeth of adults help porbeagles to gnash through tough prey.
Cool Fact — The porbeagle must keep swimming in order to breathe.
Common Max Depth — 1,120 feet
