Dorvilleids belonging to Ophryotrocha Claparède & Mecznikow, 1869 are known from deep-sea hydrothermal vents in the Pacific, Atlantic, Indian and Southern Oceans. However, how they colonized and diversified in these ecosystems has not been assessed

Four species of Ophryotrocha (Annelida, Dorvilleidae) from deep-sea reducing habitats (methane seeps on the Koryak slope and hydrothermal vents of the submarine Piip Volcano) were collected in the western part of the Bering Sea, NW Pacific. Descriptions
