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).

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).

Bayesian length-weight: a=0.00501 (0.00408 - 0.00616), b=3.07 (3.03 - 3.11), in cm total length, based on LWR estimates for this species (Ref. 93245).

营养阶层 (Ref. 69278): 4.5 ±0.0 se; based on diet studies.

Generation time: 9.2 (7.4 - 13.1) years. Estimated as median ln(3)/K based on 14 growth studies.
