Description

The hooktooth shark is a slender weasel shark from the Indo-West Pacific, from the Persian Gulf to China and Indonesia. The species grows to about 100 cm and has a streamlined, greyish body, a large mouth and long, hook-shaped teeth. As a coastal dweller it lives over the continental shelf to about 60 metres depth and hunts small fish, squid and crustaceans. It bears live young. The species is not considered dangerous, but as a shark it can bite when handled. Owing to fishing the IUCN assesses it as Endangered (EN).
