An uncommon coastal inshore and offshore pelagic species.

Biology:

Viviparous, with histotrophy; probably giving birth to only a single pup. Feeds primarily on small fishes, and to a lesser extent on planktonic crustacea; gill filter plates have a larger mesh size than other devilrays, possibly indicating a larger prey source.
