白眼鮫科 (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); isodon: iso-, from isos (Gr.), equal; odon (Gr.), tooth, allusion not explained, perhaps referring to how its teeth are similar in shape and size in both jaws [authorship often attributed to Müller & Henle, who published Valenciennes’ description]. (See ETYFish).

生態學
海洋 居於水底的; 深度上下限 0 - 20 m (Ref. 106604). 亞熱帶的; 42°N - 38°S, 100°W - 12°W (Ref. 55182)
Western Atlantic: North Carolina, USA to Cuba, the Gulf of Mexico, and southern Brazil to Uruguay (Ref. 58839). Occurrence in the eastern Atlantic, specifically in Senegal and Guinea-Bissau, have not been confirmed and may be based on Carcharhinus brevipinna (Ref. 244, 127434).
西大西洋: 美國北卡羅萊那州到古巴，墨西哥灣與巴西南部到烏拉圭.(參考文獻 58839) 在東大西洋中的發生, 特別的在塞內加爾與幾內亞比索沒有被確認, 而且可能是以 薔薇白眼鮫〔Carcharhinus brevipinna〕 為依據。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 129.0, range 119 - 139 cm
Max length : 200 cm TL 雄魚/尚未辨別雌雄; (Ref. 106604)
Commonly found close inshore. Forms large schools. Feeds on small bony fishes and cephalopods. Viviparous (with a yolk-sac placenta), 1 to 6 young per litter. Size at birth 51 to 64 cm. Presumably eaten fresh and dried salted.
普遍地棲息於近岸。 形成大群魚群。 吃小的硬骨魚類與頭足類動物。 胎生的 (具有一個卵黃囊胎盤), 每胎的 1 到 6個幼魚。 出生時的大小 51 到 64 公分。 推測為被生鮮食用與乾燥鹽醃。
Distinct pairing with embrace (Ref. 205). Viviparous, placental (Ref. 50449).西大西洋: 美國北卡羅萊那州到古巴，墨西哥灣與巴西南部到烏拉圭.(參考文獻 58839) 在東大西洋中的發生, 特別的在塞內加爾與幾內亞比索沒有被確認, 而且可能是以 薔薇白眼鮫〔Carcharhinus brevipinna〕 為依據。
