brittle-star

Any member of the echinoderm class Ophiuroidea. A brittle-star resembles a starfish, and has a small, central, rounded body and long, flexible, spiny arms used for walking. The small brittle-star Amphipholis squamata is greyish, about 4.5 cm/2 in across, and found on sea bottoms worldwide. It broods its young, and its arms can be luminous.

About 2,000 species of brittle-stars and basket-stars, whose arms are tangled and rootlike, are included in this group.
