The round rays are a family, Urolophidae, of rays found in the Indo-Pacific.

As their name implies, they have disc-shaped bodies, which are formed by wide pectoral fins that merge in front of the head. Most species have venomous spines on the tail, which is relatively long, and ends in a clear caudal fin. They range from 12 centimetres (4.7 in) to 80 centimetres (31 in) in length. ^[1]
