Ecología
marino; agua dulce; salobre asociado a arrecife; rango de profundidad ? - 500 m (Ref. 244), usually ? - 100 m (Ref. 244). Tropical; 28°N - 40°S, 88°W - 32°W (Ref. 55194)
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.

Madurez: Lm 65.0, range 80 - ? cm
Max length : 113 cm TL macho / no sexado; (Ref. 111958); common length : 75.0 cm TL macho / no sexado; (Ref. 5217); peso máximo publicado: 7.5 kg (Ref. 111958)
Common in bays and estuaries often entering rivers. Also found in offshore waters at depths of about 500 m, generally less than 100 m. Feeds mainly on small bony fishes, including wrasses, but also marine snails, squid and shrimp. Viviparous, with 2 to 6 young in a litter. Size at birth about 31 to 39 cm. Utilized salted or frozen for human consumption and processed into fish meal. Not dangerous (Ref. 9710).
Distinct pairing with embrace (Ref. 205). Viviparous, placental (Ref. 50449).
