Justification:
A small marine and brackish water stingray distributed from the southern Gulf of Mexico and the West
Indies south to Brazil. This is the most common ray species in artisanal fisheries in some states of
Northeastern Brazil (Maranhão and Paraíba). Also taken as bycatch in shrimp trawls (Ceará) and a
targeted species of sports surf fisheries (Paraíba). For some states, such as Ceará, Paraíba and Bahia,
there are increasing fishing pressures on the species, but no population assessments based on these
fisheries. Monitoring of artisanal fisheries directed towards this species, protection of breeding and
nursery grounds, population studies and more information from its range outside Brazil are all required
before the conservation status of the species can be accurately assessed.
Geographic Range
Range Description:
Western Atlantic Ocean: southern Gulf of Mexico and West Indies to Paraná State, Brazil. In Brazil
recorded from the States of Amapá, Pará (Oliveira et al. 2002), Maranhão (Lessa 1997), Ceará (Gadig et
al.2000), Paraíba (Gadig and Rosa 1993), Pernambuco (Guedes et al.1989), Bahia (Queiroz et al. 1993),
Rio de Janeiro, São Paulo (Gonzalez 1995) and Paraná (Barletta and Correa 1989). In Venezuela recorded
from the continental shelf in front of the Orinoco River delta and from the Gulf of Venezuela (Cervigón
and Alcalá 1999).
Country Occurrence:
Native: Brazil (Amapá, Bahia, Ceará, Maranhão, Pará, Paraíba, Paraná, Pernambuco, Rio de Janeiro, São
Paulo); Mexico; Venezuela, Bolivarian Republic of

Population
Current Population Trend: Unknown
Habitat and Ecology (see Appendix for additional information)
A demersal coastal marine species. Also in brackish water. Depth to 36 m. In Ceará State, Brazil there
were records of juveniles of 15-17 cm disc width (DW) in tidal pools (Furtado-Neto and Pinto 2002).
Maximum size 200 cm DW (Stehmann et al. 1978, Cervigón and Alcalá 1999). Size of birth approximately
15 cm DW (Bigelow and Schoreder 1953).
The diet of this species was studied in Ceará State (Silva et al. 2001). In all, 97 stomachs were analysed,
68.1% with food and 31.9% without. Most common food items were echinoderms (Holoturidae),
sipunculids, polychaets (Eunicidae), bivalves, gastropods and crustaceans (Penaeus, Callinectes) and
fishes (mainly Pomadasys corvinaeformis).
Systems: Marine
Threats (see Appendix for additional information)
Increasing fisheries pressure in some Brazilian States, such as Ceará (Gadig et al. 2000), Paraíba and
Bahia. In Ceará, juveniles are taken as bycatch of shrimp trawling. In Paraíba State, this species is a target
in sports surf fisheries. Currently no information from elsewhere in its range.
Conservation Actions (see Appendix for additional information)
Recommended conservation actions: monitoring of artisanal fisheries directed towards the species,
protection of breeding and nursery grounds, and population studies.
