The blacktip reef shark is one of the three most common sharks inhabiting coral reefs in the Indo-Pacific. Easily identified by the prominent black tips on its fins (especially on the first dorsal fin and the caudal fin).

Among the most abundant sharks inhabiting the tropical coral reefs of the Indian and Pacific Oceans, this species prefers shallow, inshore waters and its exposed first dorsal fin is a common sight in the region. This species typically attains a length of 1.6 m (5.2 ft).

This species predominates in shallow habitats, while the other two, the grey reef shark and whitetip reef shark are mostly found deeper. Fast-swimming and active, the blacktip reef shark may be encountered alone or in small groups.
