Brittle stars usually have five slender, flexible arms used for for locomotion. Like the sea stars, the arms are connected to a central disk. Another commonality is that mouth is found on the underside of the disk. It is rimmed by five jaws and functions as an anus as well as a mouth - a combination also known from other echinoderms.


The brittle stars are close relatives to the sea stars. They are members of the same subphylum, Asterozoa. The brittle stars are organized in two orders:

  • Euryalida is the order of the basket stars like the Gorgon's head.
  • Ophiurida includes the common star-shaped brittle stars.
