Distinguishing features

Comatulids are distinguised from all other featherstar families by having terminal segments of the oral pinnules modified to form a comb. The shape and distribution of combed pinnules is useful for distinguishing some species. They also have a distinctive "feel" due to well developed hooks on most pinnules that cause them to cling like velcro.

Comanthus suavia adults have 20 to 40 slender arms which are usually longer on one side of the animal than the other. Juveniles may have several cirri but cirri are absent in adults.

Colour pattern is distinctive across the size range: white brachials with dark articulations, although the white parts may have a pale blueish or greenish cast.

Distribution and habitat preferences

Comanthus suavia is usually found with a few arms protruding from a crevice, similar to the living positions of Comanthus parvicirrus and Comanthus gisleni.

Comanthus suavia is very common throughout the Lizard Island Group, in the lagoon, on reef slopes and in the rubble zone at the base of the reef.
