Abstract: Natural, stable, sulfur-isotope tags were used in Tsuyazaki Inlet (Kyushu, Japan) to interpret sulfur uptake by the prevailing Gastropoda and Bivalvia communities. The isotopic analyses showed that biomass with light sulfur (lowδ 34S values) derived from bacterial reduction of seawater sulfate forms the largest part of the biomass on the feeding grounds of benthos that prevail in and/or on the anoxic sediments with free sulfides, in contrast to the uptake of seawater sulfate by common benthos communities close to the open sea.
