This small electric ray occurs in very shallow water in a heavily trawled area where it is taken as bycatch in shrimp fisheries, this species is not utilized; however it may appear incidentally in markets. A poorly known species, with little information available on this small (less than 18 cm in total length) batoid, and information concerning biology, population dynamics and status are generally lacking. Due to identification difficulties, this species may be under-recorded and hence more heavily fished than currently thought. Despite this lack of information, this species is assessed as Vulnerable as a precautionary measure, given that its distribution coincides with that of intensive trawling activity.

|Habitat and Ecology:||
Common over soft substrates on the continental shelf between 2 to 130 m in depth (Fechhelm and McEachran 1984).
The maximum size known for this species is 18 cm TL (Fechhelm and McEachran 1984).
|Major Threat(s):||Bycatch in shrimp trawls is the main threat to this species, although habitat degradation may also be a problem.|
