Closeup of the central disk (aboral side) of the individual above. The aboral side of the disk is covered with small, conical spines which are larger toward the margins. It has conspicuous lobes between the arms, and may appear inflated.
-
The "dorsal" (aboral) plates on the rays are separated by small secondary plates, as can be seen here. This is a view of the aboral side of a ray. The five spines projecting from the lateral plates can be seen to the sides. The yellow tube feet can be seen projecting from the other, oral side of the ray

The underside of the mouth and the rays are white..
