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); limbatus: Latin for edged or bordered, referring to black-edged fins [authorship often attributed to Müller & Henle, who published Valenciennes’ description]. (See ETYFish).

توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0. A stout shark with a long, narrow, pointed snout, long gill slits and erect, narrow-cusped upper teeth; first dorsal fin high; no interdorsal ridge (Ref. 5578). Dark grey, ashy blue or dusky bronze on back, belly white or yellowish white; a dark band extending rearward along each side to about over origin of pelvic fin; tips of pelvic fins with a persistent black spot; tips of dorsal fins, pectoral fins, anal, and lower lobe of caudal fin usually black or dusky in young individuals, fading with growth (Ref. 9997).

An inshore and offshore shark found on or adjacent to continental and insular shelves (Ref. 244). Often off river mouths and estuaries, muddy bays, mangrove swamps, lagoons, and coral reef drop-offs (Ref. 244). Bottom associated or pelagic (Ref. 58302). Young common along beaches (Ref. 9710). Active hunter in midwater (Ref. 5485). Feeds mainly on pelagic and benthic fishes, also small sharks and rays, cephalopods and crustaceans (Ref. 5578; 37816). Viviparous (Ref. 50449). Produces litters of one to 10 young (Ref. 26938, 1602). Incriminated in very few attacks but dangerous when provoked (Ref. 244). Often taken by shore anglers (Ref. 5485). Used fresh for human consumption, hides for leather, liver for oil (Ref. 244). Parthenogenesis has been observed in a captive female (Ref. 80664).

Life cycle and mating behavior Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)

Distinct pairing with embrace (Ref. 205). Viviparous, with a yolk-sac placenta, 1 to 10 young per litter. Gestation period is 10 to 12 months. Nursery and pupping grounds are located inshore where pregnant females go to drop their young. Females are thought to spawn only every two years. Size at birth 38-72 cm (Ref. 244); 55-66 cm TL (Ref.58048).
