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);  brachyurus: a- (Gr.), not; carenatus, alternate spelling of carinatus (L.), keeled or carinate, referring to absence of dermal fold (dorsal ridge) between the dorsal fins [treated as a junior synonym of C. brachyurus by some workers]. (See ETYFish).

Short description Khóa để định loại | Hình thái học | Sinh trắc học

Các tia vây lưng cứng (tổng cộng) : 0; Tia cứng vây hậu môn: 0. A large shark to with a bluntly pointed, broad snout, narrow, bent cusps on the upper teeth, and with no interdorsal ridge (Ref. 5578). Grey to bronzy in color, white below (Ref. 5578); fins mostly plain except for dusky tips on pelvic fins, as well as dusky to black tips and rear edges on pectoral fins (Ref. 9997).

Sinh học     Tự điển (thí dụ epibenthic)

A coastal and offshore shark (Ref. 9997) found along continental margins in most tropical and temperate seas. Occasionally enters large coastal bays and inshore areas (Ref. 6390). Occasionally found near the bottom (Ref. 6808). Migratory in the northern part of its range, moving northward in spring and summer and southward in autumn and winter (Ref. 244). Feeds on pelagic and bottom bony fishes, cephalopods, and small sharks and rays (Ref. 5578). Viviparous (Ref. 50449). Undoubtedly utilized for human consumption where it occurs (Ref. 244). Implicated in shark attacks on people (Ref. 9997).

Life cycle and mating behavior Maturities | Sự tái sinh sản | Spawnings | Egg(s) | Fecundities | Ấu trùng

Viviparous, with a yolk-sac placenta. Litter contains 7 to 20 pups (Ref. 6871, 6390). Young born at 59 - 70 cm TL (Ref. 6390). Pupping may occur at any time of the year but there is a peak in births in summer (Ref. 6390). Distinct pairing with embrace (Ref. 205).
