REMARKS.Medium-sized burrowing sea anemone; only its upper part, a scapulus with the tentacles, is visible above the surface of bottom. The diameter of the tentacular crown is about 4 cm. The tentacles are dark, directed upward and slightly to the sides (i.e. they do not stand horizontally and do not touch the substrate). The tentacles are conical, probably 24 in number, usually lilac or reddish-brown or paler with two transverse dark bands of the same tint; the tips may be white. The scapulus is pale or white with a reddish-brown band in its upper part, composed of vertical lines between the insertions of the mesenteries. This color band may be poorly defined on some specimens. The scapus is covered with cuticle and firm layer of sand and gravel. One specimen of this species was photographically documented on the northern top of the Piip Volcano at 382 m, while on the Koryak slope it occurred rather often at 433– 679 m, where 65 specimens were photographed, two of which were collected.
