Species Clarkcomanthus albinotus



Distinguishing features

Comatulids are distinguised from all other featherstar families by having terminal segments of the oral pinnules modified to form a comb. Comatulids also have a distinctive "feel" due to well developed hooks on most pinnules that cause them to cling like velcro.

Twenty to 30 very slender arms, usually longer on one side of the body than the other. Very few or no cirri. A distinctive colour pattern: khaki or pale green with white patches or spots on the arms and particularly on the pinnules, giving them a beaded appearance.
