A small, spindle sharped shark with a long, rounded snout; first dorsal fin can be plain or slightly black-edged; second dorsal fin, pectoral fins and lower caudal fin with distinct black tips; a conspicuous white band on plank present.

Biology

Length: Carcharhinus sorrah can reach a maximum length of around 2.5 meters (8.2 feet). However, the typical adult size is generally between 1.5 to 2 meters (4.9 to 6.6 feet) in length.

Gestation period: 10 to 12 months Littter size: This species is viviparous, which means that live young are born. Carcharhinus sorrah normally has litter sizes between 4 and 16, but this might change based on the size and age of the female, among other things. normally has litter sizes between 4 and 16, but this might change based on the size and age of the female, among other things.

Life Expectancy: The life expectancy of Carcharhinus sorrah in the wild is estimated to be around 8 years.

Diet: The predatory spot-tail shark has a diversified food and is a carnivore. It mostly eats small bony fish, crustaceans, and cephalopods (like squid and octopuses). Given the opportunity, they will eat any available prey in their habitat because they are opportunistic feeders.

Habitat and Distribution

Habitat: Carcharhinus sorrah is a coastal and pelagic species that can be found in both marine and brackish environments. They prefer warm waters and are often associated with coral reefs, estuaries, river mouths, and coastal bays. These sharks are known to be relatively common in shallow coastal areas but can also venture into deeper waters.

Distribution: The spot-tail shark has a wide distribution across the Indo-West Pacific region. It can be found along the coasts of numerous countries, from the eastern coast of Africa to the western Pacific Ocean. Specifically, its distribution ranges from the Red Sea and East Africa to the coast of India, Southeast Asia, and northern Australia. This species is commonly encountered in the waters of countries like India, Thailand, Indonesia, Malaysia, Philippines, Papua New Guinea, and Australia. Depth: Carcharhinus sorrah typically inhabits shallow coastal waters but can also occur in deeper offshore areas. It is often found at depths ranging from 0 to 50 meters (0 to 164 feet), though it has been recorded at depths of up to 100 meters (328 feet).

Commercial Value

They are regularly caught by local artisanal and small-scale commercial fisheries ; utilised as food once landed, liver used for vitamin oil.

Threats

Overfishing, exploitation and intense fishing pressure by the fishing industry; among both sexes females are exposed to more severe fishing pressure than males.
