Habitat

This is the most commonly encountered shark in the tropical Indo-Pacific

Distribution

Indo-Pacific Ocean

Western Pacific and Indian Ocean.

Behavior

On flood tide swarms of blacktip reef sharks move over shallow reef flats. They are often seen swimming in calf-deep water with the tips of their dorsal fins breaking the surface.

Human Safety

The blacktip reef shark is often quite inquisitive when divers enter the water, but it can usually be driven off. It frequently becomes aggressive around speared fish, and this may be exacerbated by the presence of competing sharks. In these scenarios Blacktip reef sharks will rush in to take wounded fish or baits.
