Biology/Natural History: Feeds on small sea cucumbers, including Eupentacta quinquesemita, E. pseudoquinquesemita, Cucumaria miniata, C. curata, and Psolus chitonoides. May also eat tunicates such as Pyura haustor, brachiopods, and sea pens. Another common sun star, Solaster dawsoni, is an important predator of this species. May have a commensal polychaete scaleworm Arctonoe pulchra or Arctonie vittata in the ambulacral groove. A parasitic barnacle Dendrogaster sp may be inside the tissues. Eggs are 0.9 to 1 mm diameter, yellow. Juveniles often hide among tubedwelling polychaete Phyllochaetopterus prolifica.
