Black sea infralittoral fine mud
Description (English)
Fine muddy habitats situated in the lower infralittoral zone at the mouths of large rivers (Danube, Dnepr, Bug) discharging into the Northwestern Black Sea shelf. These fine muds mixed with terrestrial and freshwater detritus form soft, unstable deposits. Where the sediment content is lower in detritic organic particles terrigenous muds are more stable and sticky. In both zones the habitat is populated by bivalve molluscs and polychaete worms adapted to living in very soft substrata with high organic content. Characteristic species:Neanthes succinea, Nephthys hombergii , Abra prismatica, Mysella bidentata, Abra albaandAcanthocardium paucicostatum.
