Western Atlantic: Caribbean, including the Bahamas, south to Uruguay. The separation of this species from Rhizoprionodon terraenovae whether as a distinct species or a representative of a southern subspecies is still uncertain and pending until detailed studies are commenced.

Length at first maturity / Size / Вес / Возраст

Maturity: L_m 65.0, range 80 - ? cm
Max length : 113 cm TL самец/пол неопределен; (Ref. 111958); common length : 75.0 cm TL самец/пол неопределен; (Ref. 5217); наибольший вес (опубликованные данные): 7.5 kg (Ref. 111958)
