Hound sharks are a family, Triakidae, of ground sharks, consisting of about 40 species in 9 genera. In some classifications, the family is split in two, with Mustelus, Scylliogaleus, and Triakis in Triakidae, and the remaining genera in Galeorhinidae.

Hound sharks are small sharks with two large spineless dorsal fins and an anal fin. They are found throughout the world in warm and temperate waters, where they feed on fishes and invertebrates on the seabed and in midwater.

Most of the hound shark group are noted primarily for their commercial value. This small harmless family bears most of the features of the more renowned whaler sharks but they lack a notch in the front of the tail, called a precaudal pit, and their internal anatomy is different in having an intestine shaped like a spiral corkscrew, called a spiral intestinal valve, as apposed to a scroll valve intestine which is shaped like a rolledr.

Good source for fish tank aquariums
