Flattened dorsoventrally and rhomboidal in shape, with a long and slender tail ending in a sharp point. The head is wide and flattened, with a ventral mouth located on the underside of the body. The eyes are small and situated on the top of the head. The skin of the undulate ray is covered by a layer of dermal denticles, giving it a rough and textured feel. It has broad and triangular pectoral fins, and a well-developed caudal fin. Its colouration ranges from brown to grey, with a mottled pattern providing camouflage on the seabed. On the dorsal side, it may have darker spots and stripes, while the belly is usually lighter..
