Carcharhinidae (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); brachyurus: brachys (Gr.), short; oura (Gr.), tail, a probable misnomer since caudal fin is not short (¼ TL) and type specimens were described from mounted skins and embryos (some sources indicate name means “short-bodied”) (See ETYFish).

Carcharhinus acarenatus Moreno & Hoyos, 1983 may be a valid species. See ECoF.

A coastal and offshore shark (Ref. 9997) found along continental margins in most tropical and temperate seas. Occasionally enters large coastal bays and inshore areas (Ref. 6390). Occasionally found near the bottom (Ref. 6808). Migratory in the northern part of its range, moving northward in spring and summer and southward in autumn and winter (Ref. 244). Feeds on pelagic and bottom bony fishes, cephalopods, and small sharks and rays (Ref. 5578). Viviparous (Ref. 50449). Undoubtedly utilized for human consumption where it occurs (Ref. 244). Implicated in shark attacks on people (Ref. 9997).
