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