The wild cat shark is one of the deadliest predators in the dimly lit mesosphere, inhabiting the bottom layer of the offshore sea and feeding mainly on invertebrates. The cat shark is a cunning fish that can trap birds in the sky. The cat shark was half-floating on the surface of the sea, pretending to be dead, exposing its dark skin. Seabirds look for reefs to rest in the sea, often mistaking the half-floating cat shark for a reef and stopping to rest.
