Pontic mud with Spisula subtruncata, Syndesmia fragilis, and Cardium paucicostatum in low and variable salinity
The biocenosis has been observed in areas of low salinity in proximity of estuaries (Tiganus, 1976 describes an area in proximity of the Danube estuary). The dominant species is Syndesmia fragilis in terms of numerical presence. The biocenosis is characterised by a lower quantitative presence of Spisula subtruncata and Cardium paucicostatum, a high presence of the polychaete Melinna palmata and a rich meiobenthic fauna characterised by Kinorhyncha, Nematoda, Oligochaeta and Copepods (Tiganus 1976). The biocenosis is recently characterised by the dominant presence of the allochtonous mollusc, Mya arenaria, which has caused a variation in the composition of this biocenosis (Gomoiu 1976).
