Brittle stars consist of a central disc clearly separated from the slender, very agile and very strong arms. Ophiura albida is very similar to Ophiura ophiura and can be distinguished from this species by the absence of pores between the arm plates and by its fewer arm comb papillae. The top is reddish to orange-brown; the bottom side is dirty white.
