Ampelisca spp., Photis longicaudata and other tube-building amphipods and polychaetes in infralittoral sandy mud

English name: Ampelisca spp., Photis longicaudata and other tube-building amphipods and polychaetes in infralittoral sandy mud

Description (English)

Sublittoral stable cohesive sandy muds occurring over a wide depth range may support large populations of semi-permanent tube-building amphipods and polychaetes. In particular large numbers of the amphipods Ampelisca spp. and Photis longicaudata may be present along with polychaetes such as Lagis koreni. Other important taxa may include bivalves such as Nucula nitidosa, Chamelea gallina, Abra alba and Mysella bidentata and the echinoderms Echinocardium cordatum and Amphiura brachiata. In some areas polychaetes such as Spiophanes bombyx and Polydora ciliata may also be conspicuously numerous. This community is poorly known, appearing to occur in restricted patches. In some areas it is possible that A5.335 may develop as a result of moderate organic enrichment. A similar community in mud has also been reported in the Baltic which is characterised by large populations of amphipods such as Ampelisca spp., Corophium spp. and Haploops tubicola (see Petersen 1918; Thorson 1957) and it is not known if A5.335 is a UK variant of this biotope.
Temporal variation: In some areas of the Irish Sea this biotope is reported to be a temporal variant of units A5.244, A5.261 and A5.355. Some researchers consider these biotopes to be part of a wider muddy sand community which varies temporally depending on changes in sediment deposition and recruitment as was reported in areas of Red Wharf Bay off the Welsh coast (E.I.S. Rees pers. comm. 2002)
