REMARKS. The species forms continuous “carpets”, often near the settlements of Sagartiogeton rufus , on the most shallow-water zone of the northern top of the Piip Volcano from 349 to 394 m. The number of specimens reaches 60–70 per square decimeter, some of them were collected. Their zooids are yellow-orange, with cylindrical column up to 2–3 cm in height, encrusted with sediment particles and foraminifers; the tentacles are organized in two cycles. S. rufus and zoantharians are similar in size and color, are often located next to each other and can be confused. However, the settlements of S. rufus are sparser and other species can settle among them, while there are almost no other species of sea anemones among the zoantharians. Settlements of zoantharians were also recorded on the southern top of the Piip Volcano, but they are less numerous there. The deepest record is 478 m on the southern top of the Piip Volcano.
