Elasmobranchii (haaien en roggen) (sharks and rays) > Carcharhiniformes (Ground sharks) > 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);  acronotus: acro-, from akron (Gr.), top, summit or peak; notus, from notos (Gr.), back, allusion not explained, perhaps referring to “raised” (translation) back at first dorsal fin. (See ETYFish).

Found on continental and insular shelves, mainly over sandy, shell, and coral bottoms. Feeds on small fishes, including pinfish (Sparidae) and porcupine fish. Preyed on by larger sharks. Viviparous (with a yolk-sac placenta), with 3 to 6 young per litter. Performs a 'hunch' display, with back arched, caudal lowered and head raised, as a possible threat display when confronted by divers. Utilized dried salted for human consumption.
