Pelvetia was found on the upper shore and much Himanthalia at lower levels and in pools. In the upper littoral, there were shallow pools with rock bottoms; at lower levels, the pools often contained shingle. On the southern side of the bay there were many gullies, overhangs and crevices containing a rich anemone and sponge community. Patella was fairly common but Balanus cover was low over the whole bay. The fauna under the boulders was dominated by the tail-less lugworm Arenicola ecaudata, with other annelids.

Three major zones were distinguished. The limit of the Laminaria zone was at a depth of about 10m; its extension was restricted rather by the absence of rock than by the attenuation of light due to depth. The rock gave way to small boulders and a mixture of silty mud and coarse gravel, characterised by large species such as Axinellid sponges, Polymastia and Asterias. In a depth of about 13.5m, this zone merged into a coarse shelly sand and mud mixture with occasional rock outcrops; here sand waves indicated bottom mobility. Flustra was present on the rock as well as Axinellid sponges, while Cerianthus, Corymorpha and Cancer were prominent on the mud. At about 17m depth (point z) stones and boulders began to appear with some mud and shell debris. The stones were characterised by the presence of Alcyonidium gelatinosum and Bugula spp. together with various hydroids such as Nemertesia spp..

Pentapora foliacea and tufts of Aglaophenia tubulifera were occasionally noted. All the rocks below the algal zone possessed a dense `undergrowth fauna' of hydroids and still more numerous bryozoans such as Bugula spp. Off Pen Cristin and to the south west are several large rocky reefs rising up to 12m from the bottom. These bore a rich variety of sponges (Axinellids), anemones such as Epizoanthus couchi and Corynactis viridis as well as lobsters and crawfish.
