REMARKS. This small sea anemone (up to 2–3 cm in the height and the diameter of the tentacular crown) appears to be common on the northern top of the Piip Volcano at 347–403 m, and also photographed on the southern slope of the Piip Volcano at 668 m. It has short beige to orange-brownish column wide at the base and beige to orange transparent tentacles. White collar on the margin under the tentacles resembles a circle of pseudospherules in the extended specimens. This species detected on the vertical sides and undersides of large stones among small Sagartiidae Sagartiogeton rufus and corallimorpharians. One specimen was collected.
