A small, slender grey shark with an extremely short, broad, snout, oval eyes, 1st dorsal fin behind pectorals, 2nd dorsal nearly as large as first, conspicuous white tips on the 1st dorsal and upper caudal fin, and no interdorsal ridge. Underside lighter, sometimes dark spots on sides.

East coast, northern Natal and Mozambique; tropical Indian Ocean and Pacific.

 

Habitat

Inshore in shallow, clear waters, often on coral reefs at 8 to 40 m.

Biology
