(Ground sharks) > Carcharhinidae
Etymology: Carcharhinus: Greek, karcharos = sharpen + Greek, rhinos = nose (Ref. 45335).
Environment / Climate / Range
Marine; demersal; depth range ? - 10 m (Ref. 55182). Subtropical; 42°N - 38°S, 100°W - 12°W (Ref. 55182)
Length at first maturity / Size / Weight / Age
Maturity: Lm 123.0, range 150 - 139 cm
Max length : 190 cm TL male/unsexed; (Ref. 10731)
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.
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.
Distinct pairing with embrace (Ref. 205). Viviparous, placental (Ref. 50449).
