Phrynophiurida

The Phrynophiurida (formerly called Euryalae) are an order of brittle stars containing the basket stars.

==Characteristics== Phrynophiurida have bursae for gas exchange and excretion. Their ventral arm shields are rudimentary, and dorsal shields usually absent. Arms sometimes are branched, and can coil vertically. The vertebrae are joined by hourglass-shaped surfaces. The madreporite is on the oral surface. Digestive glands are confined to central disc. The integument is leathery, bearing calcareous granules or platelets. They generally live in deep-sea waters, coiling their arms on branched black coral.
