Abstract

This study investigates the fatty acid (FA) composition of total lipids in Quatuoralisia malakhovi Ezhova et Lukinykh, 2022 (Hemichordata: Enteropneusta), a new species of deep-sea acorn worm that was collected on the slope of the Piip Volcano in the Bering Sea. The data obtained indicate that the main components of lipids in Q. malakhovi are fatty acids of bacterial and diatom origin. The food source of the studied species is detritus containing large amounts of not only bacteria, but also diatoms. The results could be used in trophic studies of communities that include Enteropneusta.
