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 mirus is a large, cryptic or semi-cryptic crinoid with up to 40 long, slender arms and no cirri.

All known specimens of this species have an extremely large, flesh-coloured visceral mass.
