[12]:88 Like other stingrays, this species is aplacental viviparous: the embryos are initially sustained by yolk, which later in development is supplemented by histotroph ("uterine milk", containing mucus, fat, and proteins) produced by the mother. Its populations are under heavy pressure by artisanal and commercial fisheries, and by local collecting for the aquarium trade.[1]. [13] The bluespotted ribbontail ray excavates sand pits in search of molluscs, polychaete worms, shrimps, crabs, and small benthic bony fishes; when prey is located, it is trapped by the body of the ray and maneuvered into the mouth with the disc.
