Distinguishing features

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

Clarkcomanthus mirabilis adults have up to 50 rather stiff arms and no cirri. The centrodorsal plate is characteristically small in this species, compared to the surrounding radial plates. Most specimens are rather beautifully mottled brown and white or red and white.
