Whitetip Reef Shark

Overview

The Whitetip Reef Shark is a slender, medium-sized shark widely distributed throughout the tropical waters of the Indo-Pacific. It is frequently encountered by divers in shallow coral reef environments, where it is known for its docile nature and tendency to rest on the seafloor during the day.

Distribution & habitat

This species is found across the Indian and Pacific Oceans, ranging from the Red Sea and East Africa to the eastern Pacific, including the Galapagos and Cocos Islands. It is strongly associated with coral reefs, typically inhabiting clear waters at depths of 8 to 40 meters, though it can be found from the surface down to 330 meters.

Appearance

Recognizable by its slender body and short, broad snout, the Whitetip Reef Shark is most easily identified by the conspicuous white tips on its first dorsal and upper caudal fins. Its coloration is generally greyish-brown on the dorsal side with a white underside, sometimes featuring scattered dark spots. Unlike many other requiem sharks, it has a second dorsal fin that is nearly as large as the first.

Biology & behavior

Unlike many of its relatives that must swim constantly to breathe, this shark can pump water over its gills, allowing it to remain motionless on the seabed. During the day, individuals often seek shelter in caves or under ledges, frequently returning to the same resting sites for months or years. They are primarily nocturnal and are generally non-aggressive toward humans.

Feeding

Active mainly at night, these sharks use their slender bodies to navigate into narrow crevices and holes to hunt. Their diet consists primarily of bony reef fishes, crustaceans, and octopuses.

Reproduction

This species is viviparous, meaning it gives birth to live young. Females typically produce litters of one to five pups after a gestation period of 10 to 12 months, with breeding cycles occurring every two years.
