Biology

A common, but little-known inshore sluggish bottom shark (Ref. 13575) found on sandy and muddy bottoms of coastal waters, bays and inlets and rocky and coral reefs. Probably mainly feeds on bottom-dwelling invertebrates (Ref. 13575), also small fishes. Oviparous (Ref. 50449). Utilized for human consumption (Ref. 247). Possibly may occur in fresh water in the lower reaches of the Perak River in peninsular Malaysia (Ref. 43278).
