Houndsharks are a family, Triakidae, of ground sharks, consisting of about 40 species in 9 genera. In some classifications, the family is split into two sub-families, with Mustelus, Scylliogaleus, and Triakis in sub-family Triakinae, and the remaining genera in sub-family Galeorhininae.
Houndsharks are distinguished by possessing two large spineless dorsal fins, an anal fin, and oval eyes with nictitating eyelids. They are small to medium in size, ranging from 37 centimetres (15 in) to 220 centimetres (7.2 ft) in adult length. They are found throughout the world in warm and temperate waters, where they feed on fish and invertebrates on the seabed and in midwater.
