Elasmobranchi (squali e razze) (sharks and rays) > Carcharhiniformes (Ground sharks) > Carcharhinidae (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); falciformis: falx (L.), scythe or sickle; forma (L.), shape or form, referring to sickle-like shape of pectoral fins [authorship often attributed to Müller & Henle, who published Bibron’s description]. (See ETYFish).

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Spine anali: 0. A large, slim shark with a moderately long, flat and rounded snout, large eyes, small jaws, and oblique-cusped teeth with serrations; 2nd dorsal fin low and with greatly elongated rear tip (Ref. 5578). Grey or bluish-grey above, white below; no conspicuous fin markings (Ref. 5578). Only Carcharhinus species with an interdorsal ridge that has the dorsal fin origin behind the free rear tip of the pectoral fin (Ref. 26938).

Found abundantly near the edge of continental and insular shelves, but also in the open sea and occasionally inshore (Ref. 244). Often found in deepwater reefs and near insular slopes (Ref. 244). Littoral and epipelagic, in the open sea or near the bottom at 18-500 m (Ref. 58302). It is quick-moving and aggressive (Ref. 244). Solitary (Ref. 26340); often associated with schools of tuna (Ref. 244). Feeds mainly on fishes, but also squid, paper nautiluses, and pelagic crabs (Ref. 244; 37816). Viviparous (Ref. 50449). Regarded as dangerous to humans (Ref. 9997). Flesh utilized fresh and dried-salted for human consumption; its hide for leather; its fin for shark-fin soup; its liver for oil (Ref. 244). 2 to 14 young, 73 to 87 cm, are born per litter (Ref. 1602).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Viviparous, placental (Ref. 50449). 2-15 pups (Ref. 6871, 37816) born at 57-87 cm TL (Ref. 9997); 1-16 pups born at 55-72 cm TL. Females appear to breed every year, but there appears to be no reproductive seasonality (Ref. 58048). Distinct pairing with embrace (Ref. 205).
