Concept: Hydroids, ephemeral seaweeds and [Littorina littorea] in shallow eulittoral mixed substrata pools in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A1.414
Preferred label Hydroids, ephemeral seaweeds and [Littorina littorea] in shallow eulittoral mixed substrata pools
Definition Shallow pools on mixed cobbles, pebbles, gravel and sand characterised by abundant hydroids. Species present may include [Obelia geniculata], [O. dichotoma], [O. longissima], [Sertularia cupressina], [Tublaria indivisa] and [Thuiaria thuja]. The difficulty in identifying hydroids suggests many more species may be also be present. Other species typically found in this biotope include ephemeral green algae ([Enteromorpha] spp. and [Ulva] sp.), red algae ([Chondrus crispus] and Coralline algae) and the winkle [Littorina littorea]. Within the pools, patches of sand may be occupied by the lugworm [Arenicola marina] and sand mason worms [Lanice conchilega]. These pools are often associated with mussel beds (MytX), with [Mytilus edulis] frequently recorded within the pools. Barnacles ([Semibalanus balanoides] and [Elminius modestus]) and the keel worm [Pomatoceros triqueter] may be attached to shells and small stones. Mobile species typical of rock pool habitats, such as [Crangon crangon] and [Pomatoschistus minutus] will also be found within the pool.
