Ophiopeza spinosa, copyright Moorea Biocode.

Belongs within: Ophiurida.
Contains: Ophiocomidae.

The Ophiodermatidae are a group of brittle stars with the relatively stout arms inserted laterally and firmly fused with the disc (Spencer & Wright 1966).

Characters (from Spencer & Wright 1966): Arms inserted laterally and firmly fused with disc, moderately long, stout, widest at base. Granules cover disc scales of both surfaces and commonly jaws also. Unpaired infradental papillae at apex of each jaw.
