Concept: Brachiopod and ascidian communities on circalittoral rock in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A4.31
Preferred label Brachiopod and ascidian communities on circalittoral rock
Definition This habitat type occurs on the wave-sheltered, circalittoral bedrock and boulders subject to weak tidal streams. The biotopes within this complex are typically found in the Scottish sealochs (with the exception of A4.312, recorded off Ireland) and are characterised by brachipod and ascidian communities. Ascidians often recorded in this complex are [Ciona intestinalis], [Ascidia mentula], [Ascidia virginea] and [Clavelina lepadiformis]. The brachiopod [Neocrania anomala] is also characteristic of the biotopes within this complex recorded in Scottish sealochs. The polychaete [Pomatoceros triqueter], the saddle oyster [Pododesmus patelliformis], the cup coral [Caryophyllia smithii] and encrusting red algae are frequently recorded on the rocky substrata. Echinoderms such as the brittlestars [Ophiothrix fraglis], [Ophiocomina nigra] and [Ophiura albida], the starfish [Asterias rubens], [Crossaster papposus] and [Henricia oculata], the crinoid [Antedon bifida] and the urchin [Echinus esculentus] are all found in this complex. Other species present include the squat lobster [Munida rugosa], the hermit crab [Pagurus bernhardus], [Alcyonium digitatum], the anemone [Protanthea simplex] and the hydroid [Kirchenpaueria pinnata].
