Quick Summary

The family Scyliorhinidae, commonly known as cat sharks, comprises over 150 species of small, mottled sharks. These sharks typically measure less than 90 cm (3 feet) in length and are characterized by slender bodies and elongated, catlike eyes. They inhabit marine environments in tropical and temperate regions worldwide, preying on invertebrates and small fish. While some classifications place all cat sharks within the Scyliorhinidae family, others divide them into Scyliorhinidae and Pentanchidae families. The genus Apristurus, containing demon and ghost cat sharks, is notably diverse. Cat sharks are generally considered harmless to humans.1
