The Silvertip shark, Carcharhinus albimarginatus, is a fairly large and slender shark found at or close to offshore remote island reefs. The Silvertip shark is named because of its white marking on all fins. The Silvertip shark is found near reefs at depths to about 2624.67 ft (800 m), mostly below 98.43 ft (30 m), in the Red Sea and along the coasts of East Africa, Madagascar, Seychelles, Aldabra Group, Mauritius and the Chagos Archipelago, off southern Japan to northern Australia and French Polynesia, southern Baja California, Mexico to Colombia, including the Cocos Island, Galapagos and Revillagigedo islands. They tend to be fairly localized and do not migrate.
This is a fairly large but slender shark, dark gray with a white belly. It looks like most gray requiem sharks with the white tips and margins on all fins distinguishing it from its relatives. They grow to a length of 9.84 ft (3 m) and the maximum published weight is 357.59 lb (162.2 kg).
They feed mainly on benthic and midwater fish, including rays, small sharks, and occasionally cephalopods. They have been known to harass divers, but reports of attacks are very rare. This shark is seen occasionally by scuba divers and is presumably fished.
The silvertip is viviparous and usually gives birth to 5 to 11 young. The young are born after a gestation period of 12 months at a size of about 19.69 to 23.62 in (50 to 60 cm).
