Description

The starspotted smoothhound is a houndshark (Triakidae) from the northwestern Pacific. The species has a slender, greyish body with white spots and blunt, plate-like teeth with which it cracks hard-shelled prey. It lives from the intertidal zone to at least 360 m deep on mud and sand bottoms. As a bottom hunter it feeds mainly on crabs and other crustaceans, molluscs and small fishes. It is viviparous. Owing to fishing pressure the species is considered endangered. It is small and harmless to humans.
