Ophiotrichidae are a family of ophiurid brittle stars within the infraorder Gnathophiurina. All have arms with delicate translucent, thorny spines. The arms are flexible in all directions. The jaws contain clusters of well-developed tooth papillae on the apex but not on the sides. There are no mouth papillae. Inside the mouth edge there is a second pair of tube feet. They show large radial shields. The dorsal surface of the disc is covered with spines and thorny towers. ==Systematics== Ophiotrichidae contains the following genera:〔(MarineSpecies.org - Ophiotrichidae Ljungman, 1867 )〕 *''Asteria'' (''nomen dubium'') *''Gymnolophus'' Brock, 1888 *''Lissophiothrix'' H.L.
