Atlantic and Mediterranean low energy circalittoral rock

English name: Atlantic and Mediterranean low energy circalittoral rock

Description (English)

Occurs on wave-sheltered circalittoral bedrock and boulders subject to mainly weak/very weak tidal streams. The biotopes identified within this habitat type are often dominated by encrusting red algae, brachiopods (Neocrania anomala) and ascidians (Ciona intestinalis and Ascidia mentula).
