Ljungman, 1867
Description
Brittle-stars with well-developed scales, which may be more or less concealed by small spines or thorny stumps. The radial shields are large and conspicuous. Both the dorsal and ventral arm plates are well developed, the arm spines are erect and generally distinctly thorny. No mouth papillae, but a group of well-developed tooth papillae, and inside these a series of broad, strong teeth on the apex of the jaws. There is a second pair of tube-feet inside the mouth edge.
In the North Sea one species of this family is found:
- Ophiothrix fragilis
