Distinguishing features

Comasterids are distinguised from all other featherstar families by having terminal segments of the oral pinnules modified to form a comb. Comasterids a also have a distinctive "feel" due to well developed hooks on most pinnules that cause them to cling like velcro. All Oxycomanthus species have oral pinnules that end in a sharp point but this character is not useful in the field.

Oxycomanthus perplexum has up to 52 arms and up to 23 cirri.
