What Divers Should Know About Whitetip Reef Shark

Unlike many of their requiem shark relatives, the whitetip reef shark possesses the ability to actively pump water over its gills, allowing it to rest motionless on the bottom. Divers exploring Indo-Pacific coral reefs frequently encounter this species during the day, often spotting them inside caves, under ledges, or simply lying still on the sand. Typically found on or near the bottom in clear waters between 8 and 40 meters, this slender shark rarely exceeds 1.6 meters in length and is easily recognizable by its broad head and prominent white-tipped dorsal and caudal fins.

As nocturnal predators, whitetip reef sharks emerge at night to hunt bony fishes, crustaceans, and octopus. Their elongate bodies are perfectly adapted for forcing their way into crevices and holes to extract hidden prey. While generally docile and rarely aggressive towards humans, they may curiously investigate swimmers. Spear fishers should exercise caution, as these sharks have been known to attempt to steal catches. Look for their distinct oval eyes with vertical pupils and a mouth with a downward slant, giving them a perpetually 'grumpy' expression.
