Atlantic and Mediterranean moderate energy circalittoral rock

English name: Atlantic and Mediterranean moderate energy circalittoral rock

Description (English)

Mainly occurs on exposed to moderately wave-exposed circalittoral bedrock and boulders, subject to moderately strong and weak tidal streams. This habitat type contains a broad range of biological subtypes, from echinoderms and crustose communties (A4.21) to Sabellaria reefs (A4.22) and circalittoral mussel beds (A4.24).
