白眼鮫科 (Requiem sharks)
Etymology: Carcharhinus: karcharos (Gr.), sharp or jagged; rhinus, an ancient name for sharks, from rhine (Gr.), rasp, both words alluding to a shark's jagged, rasp-like skin. (See ETYFish); amblyrhynchos: In honor of British zoologist John Francis George Wheeler (1900-1979), former Director of the East African Marine Fisheries Research Organization, whose 1953 account of this shark, as C. amblyrhynchos, is the first definitive record of this species [treated as a junior synonym of C. amblyrhynchos by some workers]. (See ETYFish).

背棘 (总数) : 0; 臀棘: 0. Dark grey or bronze-grey above, white below; caudal fin with a conspicuous wide black posterior margin; undersides of pectoral and pelvic fins with black tips and posterior margins, but fins otherwise not conspicuously black or white-tipped except for white-tipped first dorsal in some individuals (Ref. 9997).

Occurs on continental and insular shelves and oceanic waters adjacent to them (Ref. 244). Common on coral reefs, often in deeper areas near drop-offs to the open sea, in atoll passes, and in shallow lagoons adjacent to areas of strong currents (Ref. 244). Coastal-pelagic near the bottom, near drop-offs at 1-275 m (Ref. 58302). Forms daytime schools or aggregations in favored areas (Ref. 244). Although active during the day, it is more active nocturnally (Ref. 244). Viviparous, with 1-6 pups (Ref. 37816). Feeds on reef fishes, squids, octopi, crabs, lobsters and shrimps (Ref. 244, 5578). Tends to be aggressive under baited conditions (Ref. 6871) and readily enters into a frenzy feeding pattern, at which time it may become quite dangerous. Repeatedly incriminated in human attacks. Utilized for human consumption, fishmeal, and other shark products. Minimum depth from Ref. 6871. Maximum length of female taken from Ref. 5213.
Viviparous, placental (Ref. 50449). 1-6 pups in a litter (Ref. 244). Gestation period about 12 months (Ref. 244). Size at birth 50 to 60 cm (Ref. 26346, 37816) or 75 cm (Ref. 244). Distinct pairing with embrace (Ref. 205).印度-太平洋: 馬達加斯加與模里西斯-塞錫爾群島的區域, 可能地印度; 也紅海到南非如果 韋氏真鯊〔Carcharhinus wheeleri〕 是與本種同種異名。 在太平洋, 它範圍從中國南部到澳洲北部與 Tuamoto 列島。
