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); signatus: Latin for marked, probably referring to indentation on outer margins of upper teeth (described from jaws only). (See ETYFish).
