Etymology: Carcharhinus: Greek, karcharos = sharpen + Greek, rhinos = nose (Ref. 45335). More on author: Rüppell.
Environment: milieu / climate zone / depth range / distribution range
; marinhas associadas(os) a recifes; intervalo de profundidade 1 - 800 m (Ref. 6871), usually 20 - ? m (Ref. 30874). Tropical; 32°N - 31°S, 31°E - 77°W (Ref. 55177)
Indo-Pacific: Red Sea and East Africa, including Madagascar, Seychelles, Aldabra Group, Mauritius and the Chagos Archipelago east to Tuamotu Is., north to Japan and south to Australia (Ref. 244). Not confirmed in west Atlantic (Ref. 58085).
Length at first maturity / Tamanho / Peso / Idade
Maturity: Lm 200.0, range 160 - 200 cm
Max length : 300 cm TL macho/indeterminado; (Ref. 2334); common length : 200 cm NG macho/indeterminado; (Ref. 30874); peso máx. Publicado: 162.2 kg (Ref. 40637)
Espinhos dorsais (total): 0; Raios dorsais moles (total): 0; Espinhos anais 0; Raios anais moles: 0. First dorsal fin and pectoral fins angular, and not expanded; upper teeth triangular; interdorsal ridge present (Ref. 1602, 5578). Dark grey or grey-brown above, white below; all fins with conspicuous white tips and posterior margins (Ref. 9997).
An inshore and offshore shark found over or adjacent to continental and insular shelves and offshore banks (Ref. 244). Prefers offshore islands, coral reefs and banks (Ref. 244). Benthopelagic (Ref. 58302). Feeds mainly on benthic and midwater fishes (including scombrids), also rays, cephalopods (Ref. 244, 1602), and small sharks and crustaceans (Ref. 89972). Viviparous (Ref. 50449). Up to 11 young, size 50 to 60 cm, are born after a gestation period of 12 months (Ref. 1602, 37816). Potentially dangerous (Ref. 9997). Presumably taken by fisheries in areas where it occurs (Ref. 9997). Caught irregularly by shark and tuna longline and tuna gillnet fisheries. Utilized for its fins (high value in adults), meat, skin and cartilage (Ref.58048). Probably utilized fresh and dried-salted for human consumption (Ref. 9997).
Viviparous, placental (Ref. 50449). With 1 to 11 pups per litter (usually 5 or 6) (Ref. 244). Gestation period is about one year, young are born in summer (Ref. 244). Size at birth 55 to 80 cm (Ref. 2334); 713-81 cm TL (Ref.58048). In southern hemisphere, both breeding and pupping occur in summer (Ref. 37816). Distinct pairing with embrace (Ref. 205).
