Cat Sharks


Catsharks and swell sharks are the common names for the members of the Scyliorhinidae family. The family members are distinguished from other similar families by the location of the last 2 gill slits behind the pectoral-fin origins, the posterior position of the first dorsal fin, the strongly asymmetrical caudal fin, the absence of keels or precaudal pits on the caudal peduncle and the comparatively large anal fin.

Members of the Scyliorhinidae are found in tropical and subtropical areas, ranging from shallow coastal waters to depths greater than 2000m. They are slow-swimming bottom-dwellers, feeding on invertebrates and small fishes.

They are the largest family of sharks, with 17 genera and 158 species worldwide.
