The humpback smooth-hound (Mustelus whitneyi) is a species of houndshark and a part of the family Triakidae.[2] The most noticeable difference between Mustelus whitneyi and its relatives, is the slight curvature, causing a "humpback" appearance located in front of its primary dorsal fin. It is found on the continental shelves of the tropical southeast Pacific, from Peru to southern Chile, between latitudes 3° S and 54° S. These sharks are demersal feeders but range from depths between 15 and 210 metres (50 and 690 ft). Humpback smooth-hound sharks are small sharks, reaching a maximum size of 118 cm (46 in) in total length.[1] Mustelus whitneyi typically feed on teleosts and invertebrates in the benthic and pelagic ecosystems, most important prey being the peruvian anchovy.[3] These humpback smooth-hound sharks are placental viviparious sharks, meaning that the embryo forms inside the mother tethered by the placental cord.[4] The threats currently causing population decline to humpback smooth-hound sharks surround issues with local fisheries and management.
