Sublittoral mud in variable salinity (estuaries)

English name: Sublittoral mud in variable salinity (estuaries)

Description (English)

Shallow sublittoral muds, extending from the extreme lower shore into the subtidal in variable salinity (estuarine) conditions. Such habitats typically support communities characterised by oligochaetes, and polychaetes such as Aphelochaeta marioni. In lowered salinity conditions the sediments may include a proportion of coarser material, where the silt content is sufficient to yield a similar community to that found in purer muds.
