REMARKS. White sea anemone was photographed on the northern slope of the Piip Volcano at the depth of 1349 m in 2016 in community of glass sponge Farrea spp. (see Rybakova et al., 2020). The tentacles are hexamerously arranged in six cycles: 6+6+12+24+48+96= up to 192 (120 tentacles are visible in the photograph). The length of the inner tentacles can be as large as the diameter of the oral disc. Brownish radial dashed lines from the base of the tentacles to the mouth extend on the oral disc above the endocoels.
