Butterfly Rays


Butterfly rays are members of Gymnuridae family. They are mainly found from the intertidal to the offshore shelf on soft bottom down to a depth of 110m, in all warm-temperate and tropical continental seas. They can be recognized by having large rounded-rhomboidal pectoral discs and short slender whip-like tails without caudal fins. Almost all butterfly rays species dorsal surface of disc and pelvic fins colour are brown, grey, or greenish above, and generally whitish below. They may or may not have spine in their tail.

Butterfly rays are slow-swimming bottom-dwellers, often found on soft mud or sand. They feed on bottom crustaceans including crabs and shrimp, bivalves, and small bottom fishes.

There is only one genus and about 16 species of butterfly rays worldwide. Malaysia is represented by 4 species.
