| Definition | Extreme upper estuarine fine sandy mud, sometimes with a fine sand fraction, in very sheltered conditions and subject to reduced salinity. An anoxic layer is usually present within the upper 3 cm of the sediment. The infaunal community is extremely poor, consisting almost exclusively of oligochaetes, including Tubificoides benedii and, more rarely, Heterochaeta costata. The only polychaete species that may occur is Capitella capitata, which may be common. The sediment may form steep banks in upper parts of macro-tidal estuaries or along saltmarsh creeks. Vaucheria species may form a film on the sediment surface along such creeks, and juvenile shore crabs Carcinus maenas may be common. At the very upper end of estuaries, the oligochaetes Limnodrilus spp. and Tubifex tubifex may be found. | |
