Corallina officinalis and Corallinaceae were both superabundant, the Corallina spp. typically overgrowing dense Mytilus edulis spat. Small algae were generally attached to the Corallina and included Audouinella, Callithamnion tetragonum and Lomentaria articulata. Pterosiphonia complanata and Mastocarpus stellatus were frequent amongst barnacles (B. perforatus, C. stellatus) and Verrucaria mucosa. Patella ulysipponensis were superabundant and may have accounted for the low, shrubby algal turf.

Mid and upper eulittoral exposed slates were characterised by dense Chthamalus stellatus and Patella ulysipponensis. Porphyra umbilicalis formed a distinctive zone in the upper eulittoral. Small shrubby red algae were present in shady spots and fissures and included Corallina officinalis and Laurencia pinnatifida. Occasional Mastocarpus stellatus and Nemalion helminthoides were present on open rock. Barnacle shells held abundant littorinids and Gammaridae were common beneath the Porphra sp. Crevices were exploited by young Mytilus.

Nutrient enrichment from abundant seabird guano resulted in numerous patches of Enteromorpha spp. and Prasiola stipitata (?). Porphyra umbilicalis extended into this zone from the upper eulittoral, as did Chthamalus stellatus. Fissures, crevices and barnacle shells were exploited by abundant littorinids, including Littorina neritoides and L. saxatilis.

Occasional red algae Corallina officinalis and Ceramium spp. Fissures held abundant Lipophris pholis and occasional Urticina felina.(Sub-habitat of 616.001.002)
