Description

The sicklefin weasel shark is a small shark of the weasel shark family (Hemigaleidae) from the Indo-West Pacific. The species grows to a little over a metre and has a slender, grey body with sickle-shaped fins and a small mouth. It is a fairly common inhabitant of tropical coastal and shelf waters. It feeds mainly on squid and other cephalopods. It is viviparous. Owing to fishing pressure the species is considered vulnerable. It is small and not dangerous to humans, although it may bite when handled.
