Blacktip Reef Shark

Overview

The Blacktip Reef Shark is a common, wide-ranging requiem shark frequently encountered in the tropical and subtropical waters of the Indo-Pacific. It is highly recognizable by the prominent black tips on its fins, which are often highlighted by a white band, and it is frequently seen patrolling shallow reef flats and lagoons.

Distribution & habitat

This species is widely distributed throughout the Indian and Pacific Oceans, ranging from East Africa and the Red Sea to the Hawaiian Islands and the Tuamotu Archipelago. It is also found in the eastern Mediterranean via the Suez Canal. These sharks prefer shallow, inshore environments, including coral reefs, reef ledges, and sandy flats, though they are occasionally found in brackish or freshwater areas.

Appearance

This is a stocky, moderate-sized shark with a short, bluntly rounded snout and oval eyes. Its coloration is typically yellow-brown or bronze on the upper body, fading to white on the underside. A defining feature is the conspicuous black or dark brown tips on all fins, particularly the first dorsal fin and the lower lobe of the caudal fin. A distinct white band often runs along the flanks, extending toward the pelvic fins.

Biology & behavior

Blacktip Reef Sharks are active predators that exhibit strong site fidelity, often remaining within a small home range for years. They are known to be inquisitive and may approach divers, though they are generally shy. They are viviparous, with females giving birth to small litters of two to five pups after a long gestation period.

Feeding

They primarily hunt small bony fish, cephalopods, and crustaceans. Their diet may also include sea snakes and seabirds.
