This is a small family consisting of 7 species, divided in 4 genera. With the exception of the snaggletooth shark, Hemipristis elongatus, which can reach a size of up to 240cm, weasel sharks are mostly small to moderate-sized animals with horizontally oriented oval eyes, internal nicitating membranes and spiraculi. Weasel sharks are close related to the requiem sharks (Carcharhinidae) and have similar features. The origin of the first dorsal fin is close to the pectoral fin bases. A precaudal pit is present. They are found in coastal tropical areas down to 100m. Their distribution is limited to the Atlantic and continental Indo-West Pacific. They feed on a variety of small fishes, crustaceans and echinoderms. They all give birth to live young (placental viviparity).
