Map Of The Whitecheek Shark’s Habitat

Whitecheek Shark Habitat Map

Whitecheek sharks inhabit continental shelves and inshore slopes in the Indo-Western Pacific Ocean, down to around 170 m (560 ft) below sea level. They are commonly found between the latitudes 34°N and 25°S, which includes the Arabian Sea, the Persian Gulf, Java, Indonesia, Japan, and Australia.



Its main prey is fish, but it also feeds on octopuses, squid, and various crustaceans such as crabs. It also occasionally hunts worms andmollusks laying on the seabed.


The females of this species are viviparous and breed throughout the year. Litters usually have two pups, but they can have up to four. The pups measure about 38 cm (15 in) at birth. Both sexes mature at a length of around 70 cm (28 in).


Like other sharks, the whitecheek shark has an acute sense of smell and vision, a smooth, streamlined body, and sharp serrated teeth for hunting.
