MATERIAL. LV-75-3, 55.4160°N 167.2732º E – 55.4161°N 167.2739ºE, depth 382– 351 m, many specimens photographed; LV-75-8, 55.4161°N 167. 2736ºE – 55.4163°N 167.2750ºE, depth 377–400 m, many specimens photographed; LV-75-9, 55.4156°N 167.2736ºE – 55.4160°N 167.2743ºE, depth 388– 350 m, many specimens photographed.

LV-82-1, 55.4171°N 167.2773ºE – 55.4160°N 167.2744ºE, depth 386– 373 m, several specimens collected (samples 6 and 7) and many specimens photographed.

REMARKS. Numerous small (up to 2 cm in height) rose-orange specimens form crowded settlements on the northern top of the Piip Volcano, often together with zoantharians Epizoanthus sp. of similar size and color. However, the settlements of Sagartiogeton rufus are sparser than the settlements of the zoantarians. Sometimes they form settlements near the hydrothermal sites together with filamentous colonies of bacteria. This species has not been found elsewhere. Several specimens were collected.
