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.
The bluespotted ribbontail ray searches for food in sand pits by digging them up. It then captures prey like molluscs, polychaete worms, shrimps, crabs, and small bony fishes by trapping them with its body and moving them towards its mouth using a disc-like structure.
