Concept URI	http://eunis.eea.europa.eu/eunishabitats/A5.34
Preferred label	Infralittoral fine mud
Definition	Shallow sublittoral muds, extending from the extreme lower shore to about 15-20 m depth in fully marine or near marine conditions, predominantly in extremely sheltered areas with very weak tidal currents. Such habitats are found in sealochs and some rias and harbours. Populations of the lugworm [Arenicola marina] may be dense, with anemones, the opisthobranch [Philine aperta] and synaptid holothurians also characteristic in some areas. The extent of the oxidised layer may be shallow with some areas being periodically or permanently anoxic. In these areas bacterial mats may develop on the sediment surface. Infaunal records for this habitat type are limited encompassing only one biotope. They are therefore not representative of the full suite of infaunal species found in this biotope.
