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); cautus: Latin for nervous or wary, the “Nervous Shark” mentioned in Whitley (1940), referring to how the “slightest splashing” in shallow water caused this shark to “dash away at great speed into deep water”. (See ETYFish).
