“…However, the large phylogenetic distance between molluscs living off the Southern Asian coast and the Bering Sea likely indicates the absence of a recent faunistic exchange between the regions. Similar phylogenetic relationships were observed in the recently described Astyris axicostata Kantor, Zvonareva et Krylova, 2023, which has closest relatives in the Okinawa Trough and the Sea of Japan [22]. Astyris axicostata is also known only from the Piip Volcano, however, this species has been observed both in geothermally active locations and in areas without marked geothermal activity [7,22].…”

Therefore, it is not completely clear whether this species is an obligate inhabitant of the chemosynthetic zone.…”

The benthic macrofauna of Arctic and subarctic seas is mainly represented by widespread species and is generally devoid of endemics. The exceptions are reduced habitats, such as cold seeps, hydrothermal areas, and wood falls, which include endemics of at least the species level. A detailed study and analysis of such endemics allows us to understand the mechanisms of colonization and to assess the age of the fauna of high-latitude marine regions. Here, the new species Provanna annae sp. nov. is described from the geothermal zone of the Piip volcano in the Bering Sea (subarctic Pacific) based on the morphological and molecular phylogenetic data. The new species appears to be the northernmost and one of the most shallow-water species among the known representatives of the family and is suggested to be endemic to the region. The new species is related to a group of Provanna species from reducing habitats off Japan. Composition of the gut content indicates that the new species bottom sediments. Bacteria are found on the gills of the mollusc and are probably symbionts that also provide nutrition. This type of mixotrophic feeding is rare in gastropods and may be a unique feature among Caenogastropoda.

“…Early studies of video and still images and collected specimens showed that the benthic communities were characterized by a high abundance and diversity of meio-, macro-and megafauna, with a pronounced vertical and horizontal zonation in faunal distribution (Sanamyan et al, 2018(Sanamyan et al, , 2021Galkin, Ivin, 2019;Galkin et al, 2019;Vinogradov and Galkin, 2019;Adrianov and Maiorova, 2020;Mordukhovich et al, 2020;Rybakova et al, 2020;Garlitska et al, 2022;Menshenina and Tabachnik, 2022;Tabachnik et al, 2022;Kantor et al, 2023;Nekhaev, 2023).…”

The aim of the work was to study some deep-sea bottom communities of the Far Eastern seas of Russia using a remotely operated underwater vehicle.Materials were the data of underwater video and photo profiling, as well as direct sampling, performed in 2011–2013, 2016, 2018, 2020 and 2021.As results, an extensive array of new data on the composition, structure, and patterns of distribution of deep sea biota has been obtained. A primary description of the benthic communities of the Gamovsky Canyon (Sea of Japan), cold seeps of the Deryugin Basin (Sea of Okhotsk), and Piip underwater volcano (Bering Sea) has been prepared. Some features of the composition and structure of communities are revealed, and vertical zonality is described.Practical value: the results can be used in the development of environmental protection measures and measures of rational nature management in the waters of the Far Eastern seas of Russia and in areas of potential development of deep-sea mineral resources in the ocean.
