Preferred label [Fucus serratus] with sponges, ascidians and red seaweeds on tide-swept lower eulittoral mixed substrata
Definition Sheltered lower shore boulders, cobbles and pebbles on muddy sediments that are subject to enhanced tidal water movement and characterised by a species rich community. Dominant species include the sponges [Halichondria panicea] and [Hymeniacidon perleve], the sea squirts [Ascidiella aspera], [Ascidiella scabra], [Styela clava] and [Botryllus schlosseri]. A number of filamentous red seaweeds including [Halurus flosculosus], [Ceramium] spp., [Gracilaria gracilis, Polysiphonia fucoides] and foliose seaweeds [Mastocarpus stellatus] and [Chondrus crispus] are usually present. The brown seaweed [Dictyota dichotoma] and the wrack [Fucus serratus] with colonies of the hydroid [Dynamena pumila], and [Ectocarpus] sp. may be found on more stable substrata. Boulders and large cobbles provide substrata for the top shell [Gibbula cineraria], the whelk [Nucella lapillus] and barnacles such as [Semibalanus balanoides, Balanus crenatus], or in areas with variable salinity [Elminius modestus], and the tube-forming polychaete [Pomatoceros triqueter]. Patches of sand or mud are often characterised by the polychaete [Lanice conchilega] and the polychaete [Sabella pavonina]. Aggregations of the mussel [Mytilus edulis] and, in southern and eastern England the limpet [Crepidula fornicata], may be found attached to cobbles and pebbles. Sites in Scottish sea lochs may support maerl [Lithothamnion] spp. and bivalves [Venerupis senegalensis] (see also VsenMtru). Situation: This biotope is found above a community dominated by kelp such as [Laminaria digitata] (Ldig) or seagrass beds dominated by [Zostera marina] (Zmar) depending on the substrata found below. It is found below biotopes dominated by wrack [Fucus vesiculosus] (Fves) or [M. edulis] beds (MytFab; Myt.Myt).
