The blackspot shark is a relatively slender species with a streamlined appearance, growing to a length around 95 cm (37 in).

The eyes are large, oval, and set horizontally, and are protected by a nictitating membrane on the lower side.

Usually, 12 tooth rows occur on either side of both top and bottom jaws, but the number can vary from 11 to 13.

The first dorsal fin is long, narrow, and curved (falcate) and has a short rear tip.

It is either pointed or narrowly rounded at the apex and its origin is directly over the free posterior end of the pectoral fins.

The caudal fin is about one-fifth of the total length of the shark, the dorsal lobe is elongated and has a notch in the lower margin near the tip and the ventral lobe is smaller, markedly falcate, and has a more rounded tip.

[6] The blackspot shark is native to the Indian and Pacific Oceans, where it is found on the continental shelves and shallow water around islands from the surf line to depths of about 40 m (130 ft).

[3] The blackspot shark feeds on small fish, crustaceans, and squid, and is not dangerous to man.
