Preferred label	Circalittoral faunal communities in variable salinity
Definition	This habitat type occurs on wave-sheltered, variable salinity bedrock and cobbles, subject to moderately strong to weak tidal streams. This complex contains a suite of sponges able to tolerate the variable salinity conditions like [Hymeniacidon perleve], [Suberites ficus], [Halichondria panicea], [Halichondria bowerbanki], [Cliona celata] and [Leucosolenia botryoides]. The barnacle [Balanus crenatus] is frequently recorded in this complex. A sparse hydroid/bryozoan turf composed primarily of [Nemertesia antennina], [Nemerteis ramosa], [Plumularia setacea], [Alcyonidium diaphanum] and [Bugula plumosa] is often recorded. Other species recorded are the ascidians [Clavelina lepadiformis], [Morchellium argus] and [Dendrodoa grossularia], the anemones [Metridium senile] and [Sagartia troglodytes], the starfish [Asterias rubens] and the crab [Carcinus maenas].
