See text Culcita novaeguineae (common name, cushion star) is a species of starfish.

Culcita novaeguineae has numerous synonyms, at least in part because it has a "goniasterid" phase; the juveniles exhibit little resemblance to the mature form, and gradually change in morphology as they grow.

The colour is very variable and includes a mottling with darker and lighter shades of fawn, brown, orange, yellow and green.

[3] The armoured body wall is made of calcareous ossicles which are supported internally by pillars which buttress the ambulacra.

The small shrimp Periclimenes soror lives as a commensal hiding under the cushion star.
