Infralittoral mud
Description (English)
Sublittoral mud and cohesive sandy mud extending from the extreme lower shore to the lower limit of vascular plants. This biotope is predominantly found in sheltered harbours, sealochs, bays, marine inlets and estuaries and stable deeper/offshore areas where the reduced influence of wave action and/or tidal streams allow fine sediments to settle. Such habitats are often by dominated by polychaetes and echinoderms, in particular brittlestars such as Amphiura spp. Estuarine muds tend to be characterised by infaunal polychaetes and oligochaetes.
