The water vascular system includes a number of small tube feet that become stiff when water is pushed into them, allowing the sea star to move on a conveyor belt-like rotation of feet. Ophiuroida move horizontally, and Euryalina species move vertically. The World Ophiuroidea Databaselists over 2,000 species of brittle stars accepted in theClass Ophiuridea, the taxonomic class whichcontains brittle stars, as well as basket stars and snake stars (Kingdom: Animalia, Phylum: Echinodermata, Class: Ophiuroidea, Order: Ophiurida).

Of all echinoderms, the Ophiuroidea may have the strongest tendency toward five-segment radial (pentaradial) symmetry. Ophiuroids can readily regenerate lost arms or arm segments unless all arms are lost. Perceived threats include pollution and habitat loss.

A brittle star fossil from Western Australia has revealed the starfishes lived 275 million years ago. While some of them will often live peacefully in reef tanks for years. [3] Basket stars are usually confined to the deeper parts of this range; Ophiuroids are known even from abyssal (>6,000 m) depths. Serpent (Brittle) stars are able to detach their arms as diversion tactics in a bid to escape predators, and they can regenerate the lost arms or arm segments after some months. They use their thin arms for locomotion; by rowing their flexible arms, these creatures are able to make fairly fast jerk movements on the aquarium floor. The World Ophiuroidea Database.
