Their long, thin arms—usually five and often forked and spiny—are distinctly set off from the small disk-shaped body. The arms readily break off but soon regrow. Among the basket stars, a type of brittle star, each arm may branch multiple times, and the outstretched arms reach nearly 3 feet across. Most basket stars live in deep water. These Brittle stars were found in 1 – 3 feet of water by turning over rocks.
