WHAT TO LOOK FOR
A large shark with striking white tips and trailing edges on all fins.

COLOR

Dark grey, and sometimes bronze-tinged above, white below.

SIZE
When born, the shark is 2.1 to 2.2 ft [63 to 68 cm] in length. Males mature at a length of 5.2 to 5.9 ft [1.6 to1.8 m], while females mature at 5.2 to 6.5 ft [1.6 to1.9 m]. Their maximum length is approximately 9.8 ft [3 m].

TEETH
Upper teeth are triangular.

HABITAT
They prefer the continental shelf, offshore islands, coral reefs, and offshore banks. They can also be found inside lagoons, near drop-offs and offshore, from the surface to depths of 1968.5 to 2624.7 ft [600 to 800 m]. These sharks are not oceanic. The young sharks are found more often in shallower water close to the shore, while adults are more wide ranging.

DISTRIBUTION
Tropical Indo-Pacific Ocean, and are widely but patchily distributed. They are unconfirmed in the west Atlantic.

BIOLOGY
Prey – A variety of mid-water and bottom fishes, eagle rays, and octopi.
Reproduction – These sharks are viviparous, with yolk-sac placenta and 1-11 pups per litter, but often 5-6, after about a 1 year gestation period.

BEHAVIOR
These sharks range from the surface to the bottom, but may not disperse widely between sites. They often follow boats. They are more aggressive and dominant than the Galapagos shark and the blacktip shark. Adults are often scarred. These sharks are large, bold, and potentially harmful. There has been one confirmed shark-bite incident. Caution is advised when encountering this shark underwater.

STATUS
IUCN Red List: Not Evaluated. These are slow-growing sharks, and remote populations are likely to be highly vulnerable to target fisheries for meat or fins, particularly if they have a limited dispersion between sites.
