Diet / Feeding
Diet
- Blacktip reef shark prefers fish, but also feeds on crustaceans, cephalopods and other mollusks.
- Common prey includes surgeonfish and mullet. In inshore mangrove areas, this shark will also consume snakes.
Feeding Behaviors
- Has long, thin, serrated teeth, which help in eating reef fish.
Range / Habitat
Range
- Occurs in the Indo-Pacific from the Red Sea and East Africa to the Hawaiian Islands and south to French Polynesia. It also has moved into the eastern Mediterranean through the Suez Canal.
Habitat
- Found in shallow inshore waters on coral reefs, in the intertidal zone (reef flats) and near reef drop-offs. Also found in mangrove areas, moving in and out with the tide. Has been observed in fresh water, but not in tropical lakes and rivers far from the sea.
- Usually found in depths 65 to 246 feet (20-75 m).
Reproduction & Growth
- Female blacktip reef shark produces two to four pups, measuring 1.5 to 1.7 feet (46-52 cm), after an 8-16-month gestation period, which is thought to vary due to water temperature.
Conservation Status
- “Near Threatened” on the IUCN Red List.
Additional Information
- This shark cruises in very shallow water with its dorsal (top) fin often extending above the surface. It has been known at times to jump completely out of the water while in the shallows.
- Blacktip reef shark may become aggressive in areas where spear fishing is common.
- It is regularly caught by inshore fisheries and is vulnerable to depletion because of its small litter size and long gestation period. It is generally sold as fillets, its fins are valued for shark-fin soup and the liver as a source of oil.
- This species is found singly or in small groups.
- Blacktip reef shark is not to be confused with the blacktip shark, which is a different species.
