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); brachyurus: a- (Gr.), not; carenatus, alternate spelling of carinatus (L.), keeled or carinate, referring to absence of dermal fold (dorsal ridge) between the dorsal fins [treated as a junior synonym of C. brachyurus by some workers]. (See ETYFish).
