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).

生物学特性     字汇 (例如 epibenthic)

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).

大量地在大陆架和岛屿棚边缘的附近发现, 也在开放海域中与偶然近海.(参考文献 244) 时常发现于深水礁区与在岛的斜坡附近.(参考文献 244) 移动快速与侵略性它是。 (参考文献 244) 独居性;(参考文献 26340) 时常伴随着鲔鱼群.(参考文献 244) 主要吃鱼, 也捕食乌贼, 纸鹦鹉螺 , 与大洋性螃蟹 (参考文献 244; 37816)。 胎生的.(参考文献 50449) 被认为了对人类具有危险性.(参考文献 9997) 鱼肉利用生鲜或乾渍供人类消费; 它的隐藏用做皮革; 它的鳍用做鱼翅汤; 它的肝脏用于制造鱼肝油.(参考文献 244) 生产2 到 14 只, 73 到 87 公分的幼鱼每胎。 (参考文献 1602)

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).Circumtropical。 西大西洋: 美國麻薩諸塞州到巴西南部, 包括墨西哥灣與加勒比海。 東大西洋: 西班牙, 馬得拉群島到安哥拉北部; 聖保羅岩礁;(參考文獻 13121) 維德角.(參考文獻 34514) 印度-太平洋: 分散的來自紅海與南非的納塔爾 (參考文獻 5578) 的紀錄到中國,紐西蘭, 與加羅林群島,夏威夷語,鳳凰島與列島群島。 東太平洋: 墨西哥的下加利福尼亞南部到智利北部。 高度遷移的種,1982年海事法會議的附件一.(參考文獻 26139)
