Asteronychidae Asteroschematidae Gorgonocephalidae Euryalidae The Euryalina are a suborder of brittle stars,[1] which includes large species with either branching arms (called "basket stars") or long and curling arms (called "snake stars").
Many of them live in deep sea habitats or cold waters, though some basket stars can be seen at night in shallow tropical reefs.
Most young basket stars live on specific type of coral.
Like other echinoderms, basket stars lack blood and achieve gas exchange via their water vascular system.
[4] The fossil record of this group is rather poor and only dates back to Carboniferous.
