The whitetip reef shark is a species of requiem shark, in the family Carcharhinidae. It is the only extant species of genus Triaenodon. A small shark that does not usually exceed 1.6 m (5.2 ft) in length, this species is easily recognizable by its slender body and short but broad head, as well as tubular skin flaps beside the nostrils, oval eyes with vertical pupils, and white-tipped dorsal and caudal fins. One of the most common sharks found on Indo-Pacific coral reefs, the whitetip reef shark occurs as far west as South Africa and as far east as Central America. It is typically found on or near the bottom in clear water, at a depth of 8–40 m (26–131 ft).

Whitetip Reef Shark is slim, with a short, broad, flattened head and bright white tips on its first dorsal fin and the top of its tail. By day it rests on the bottom in caves, which it can do because it pumps water over its gills. Grey Reef Shark must keep swimming to breathe; it is stockier, has no white tips in the Pacific, and has a broad black band along the rear edge of its tail.
