Siboglinids (Annelida, Siboglinidae) as possible indicators of carbohydrates on the case of the Sea of Okhotsk Geographical and bathymetric distribution of siboglinides in the sea of Okhotsk was studied. More than 75% of all siboglinides were found at a depth of 400 m. These findings were mainly concentrated in the North-Western part of the shelf. A comparison of the distribution of siboglinides in the Sea of Okhotsk and generalized geological data on the distribution of hydrocarbons showed that siboglinides in the sea of Okhotsk were mostly found in the areas of hydrocarbon manifestations and were absent in the central regions, where in the bottom sediments and in the near-surface layer of water we have registered minimal methane and hydrocarbon concentrations.
