Basket star

The Euryalina are a suborder of brittle stars, which includes large species with either branching arms (called "basket stars") or long and curling arms (called "snake stars"). It is sometimes listed as the order Euryalida.

Many species live in deep sea habitats or cold waters, though some basket stars can be seen at night in shallow tropical reefs.
