The composition of the macrobenthos from areas of submarine geothermal vents in the Romanian shallow waters of thc Black Sca is analysed in the paper. Twelve macrobenthic species were observed which well resist to the levels of H2S, four of them being more numerous in the waters with H2S than in the normal ones (Fabricia sabella, Capitella capitata, Middendorfia caprearum and Hydrobia pontieuxini). A rich sulfur-oxidizing chemoautotrophic microbiological community was identified near the vents both on living organisms and on incrt substrata. The bacteria constitute an abundant primary food source for some opportunistic species with high ecological tolérances.
