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).

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).
Length at first maturity / サイズ / 重さ / 年齢
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.
