Classification / Names Noms communs | Synonymes | Catalog of Fishes(Genre, Espèce) | ITIS | CoL | WoRMS | Cloffa

Élasmobranches (requins et raies) (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);  isodon: iso-, from isos (Gr.), equal; odon (Gr.), tooth, allusion not explained, perhaps referring to how its teeth are similar in shape and size in both jaws [authorship often attributed to Müller & Henle, who published Valenciennes’ description]. (See ETYFish).

Environment: milieu / climate zone / depth range / distribution range Écologie

marin démersal; profondeur 0 - 20 m (Ref. 106604). Subtropical; 42°N - 38°S, 100°W - 12°W (Ref. 55182)

Western Atlantic: North Carolina, USA to Cuba, the Gulf of Mexico, and southern Brazil to Uruguay (Ref. 58839). Occurrence in the eastern Atlantic, specifically in Senegal and Guinea-Bissau, have not been confirmed and may be based on Carcharhinus brevipinna (Ref. 244, 127434).

Biologie     Glossaire (ex. epibenthic)

Commonly found close inshore. Forms large schools. Feeds on small bony fishes and cephalopods. Viviparous (with a yolk-sac placenta), 1 to 6 young per litter. Size at birth 51 to 64 cm. Presumably eaten fresh and dried salted.
