The scales on the central disc of Ophiocoma valenciae are encrusted with granules that become more pointed along the edges and are quite delicate. The disc itself is generally a monotonous shade, ranging from a subdued green to a dark brown, sometimes displaying a mottled green appearance. The arms are typically greenish or greenish-brown and may feature deep brown, cream, or darker bands. The arm spines are as long as the width of the arms.
