	Echinoderms (starfish, brittle star, sea urchin, feather star, sea cucumber)
		Serpent stars feed mostly on small invertebrates like mollusks, worms and crustaceans and are generally found in crevices and beneath rocks or in holes in the sand.
		Snake stars (for example Ophiothela danae) are found entwined in the branches of fl corals or gorgonians where they feed on the rich mucus of their host, in turn performing cleaning functions.
		Brittle stars are the most active and fastest moving echinoderms.

	The Brittle Star
		Brittle stars are one of the most fascinating scavengers found in reef tanks.
		Usually a member of the "clean up crew," brittle stars reside in live rock and consume detritus, catching food as it is carried on the current.
		Brittle stars are reef safe and make a good contribution to almost any system.

	Wet and Salty: Brittle Star (Site not responding. Last check: 2007-10-19)
		Brittle stars are echinoderms, which means that they're related to starfish (or more accurately, sea stars.) They have pentamerous radial symmetry, which means that they have 5 arms arranged around a central disk.
		Unlike their somewhat passive cousins the sea stars, brittle stars are relatively fast, and their thin, whip-like arms tend to writhe independently of each other when the animal is disturbed.
		Closely related to brittle stars, basket stars (which have long tangled arms, hence the name) are also Ophiuroids.

		Brittle Stars are carnivorous detrivores that dine largely on plankton, supplemented with organic matter on hard surfaces and occasionally small animals such as muscles and worms1.
		Occasionally brittle stars have been known to prey on other brittle stars for their stomach contents if food is scarce.10 High energy waves can do as much or more damage to a population than predators can.

	Brittle star - Wikipedia, the free encyclopedia
		Brittle stars are echinoderms, closely related to sea stars.
		However brittle stars are also common, if cryptic, members of reef communities, where they hide under rocks and even within other living organisms.
		Brittle stars move fairly rapidly by wriggling their arms which are highly flexible and enable the animals to make either snake-like or rowing movements.

		Ophiuroids are a large group (over 1600 species) of echinoderms that includes the brittle stars (Ophiurida) and basket stars (Euryalida).
		However, brittle stars have long, flexible arms (hence the other common name for ophiuroids, "snake stars" and a central, armored, disk-shaped body that is clearly demarcated from the arms.
		Ophiuroids are not common fossils; as you might expect from the name "brittle star", ophiuroids rapidly fall to pieces after death, and are rarely preserved whole.

		Only at night does the brittle star venture out of its hiding place to snake across the surface of the reef because shining a light on an outstretched limb might just cause the animal to hide.
		Brittle stars are echinoderms—relatives of sea stars and sea urchins—and can be distinguished from the other groups by their long, thin, highly flexible arms and their small central disk.
		Because the dorsal surface of the brittle star is covered with thousands of tiny “eyes,” though, and each eye receives light from a slightly different direction and angle, the entire surface can act as one large compound eye.
