Mixed faunal turf communities on circalittoral rock

English name: Mixed faunal turf communities on circalittoral rock

Description (English)

This habitat type occurs on wave-exposed circalittoral bedrock and boulders, subject to tidal streams ranging from strong to moderately strong. This complex is characterised by its diverse range of hydroids (Halecium halecinum, Nemertesia antennina and Nemertesia ramosa), bryozoans (Alcyonidium diaphanum, Flustra foliacea, Bugula flabellata and Bugula plumosa) and sponges (Scypha ciliata, Pachymatisma johnstonia, Cliona celeta, Raspailia ramosa, Esperiopsis fucorum, Hemimycale columella and Dysidea fragilis) forming an often dense, mixed faunal turf. Other species found within this complex are Alcyonium digitatum, Urticina felina, Sagartia elegans, Actinothoe sphyrodeta, Caryophyllia smithii, Pomatoceros triqueter, Balanus crenatus, Cancer pagurus, Necora puber, Asterias rubens, Echinus esculentus and Clavelina lepadiformis.
