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)

Distribution Pays | Zones FAO | Écosystèmes | Occurrences | Point map | Introductions | Faunafri

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).

Length at first maturity / Taille / Poids / Âge

Maturity: Lm 129.0, range 119 - 139 cm
Max length : 200 cm TL mâle / non sexé; (Ref. 106604)

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.
