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); sorrah: Tamil (Indian subcontinent) word for shark [authorship often attributed to Müller & Henle, who published Valenciennes’ description]. (See ETYFish).

Found on the continental and insular shelves, primarily near reefs (Ref. 244). Sometimes in offshore waters (Ref. 30573). Live near the seabed during the day and near the surface at night (Ref. 6390). Feeds on bony fishes (Ref. 68964). Shark movements often short (50 km) but may be more than 1,000 km (Ref. 6390). Prefers teleost fishes but also feeds on cephalopods and crustaceans (Ref. 6871). Viviparous (Ref. 50449). Regularly caught by local artisanal and small-scale commercial fisheries where it occurs (Ref. 244). Utilized as a food fish; fins used in the oriental shark fin trade, liver for vitamin oil, and offal for fishmeal (Ref. 9997).

Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Viviparous, with a yolk-sac placenta (Ref. 244). Pups, average 3, range 1-8, are produced in January after a 10-month gestation period. Average length at birth is 50 cm TL. Length increases by about 25 cm during the first year. These sharks breed once each year (Ref. 13440). Distinct pairing with embrace (Ref. 205).印度-西太平洋: 紅海與東非 (包括馬達加斯加，模里西斯與塞錫爾群島) 到菲律賓,北至中國, 南至澳洲。 也從 Vanikolo 島 (聖克魯斯群島) 與索羅門群島。 可能出現在亞丁灣，阿曼灣與斯里蘭卡。 (參考文獻 9997)
