Concept URI	http://eunis.eea.europa.eu/eunishabitats/A4.21
Preferred label	Echinoderms and crustose communities on circalittoral rock
Definition	This habitat type occurs on wave-exposed, moderately strong to weakly tide-swept, circalittoral bedrock and boulders. Echinoderms, faunal ([Parasmittina trispinosa]) and algal crusts (red encrusting algae) dominate this biotope, giving a sparse appearance. Typical echinoderms present are the starfish [Asterias rubens], the brittlestar [Ophiothrix fragilis] and the sea urchin [Echinus esculentus]. There may be isolated clumps of the hydroids [Nemertesia antennina] and [Abietinaria abietina], [Alcyonium digitatum], the anemone [Urticina felina] and the cup coral [Caryophyllia smithii]. Other species present may include the polychaete [Pomatoceros triqueter] and the top shell [Calliostoma zizphinum].
