The Sandbar Shark (Carcharhinus plumbeus) is a marine (saltwater) fish in the Carcharhinidae family of requiem sharks. It is an elasmobranch cartilaginous fish — a fish that does not have a bony skeleton. It is also known as the Thickskin Shark or the Brown Shark. It is related to the Bull Shark.
The Sandbar Shark has a bluish-grey or brownish-grey streamlined body, with a very high, triangular dorsal (back) fin and long pectoral fins. It has a white underbelly. It has a broad, rounded snout and large, round eyes. The upper and lower jaws each have 13 or 14 triangular-shaped teeth.
It measures about 188-250 centimetres (74-98 inches) in length. The female is larger than the male.
It is common in the Indian Ocean and the Pacific Ocean, from the waters off Easter Island to South Africa, as well as the Atlantic Ocean. It likes shallow waters, estuaries, sandbars, and coral reefs.
The Sandbar Shark is a fast swimmer. It is a nocturnal apex predator. It hunts at night, eating other fish, rays, crabs, and octopuses.
It is solitary or it forms a same-sex group of 5-20 individuals. It often shares its territory with Grey Reef Sharks.
The Sandbar Shark is viviparous. After a 12-month pregnancy, the female Sandbar Shark gives birth to about 8 live young, called pups.
