Preferred label Anemones, including [Corynactis viridis,] crustose sponges and colonial ascidians on very exposed or wave surged vertical infralittoral rock
Definition Vertical very exposed and exposed bedrock gullies, tunnels and cave entrances subject to wave-surge dominated by sponge crusts such as [Clathrina coriacea, Myxilla incrustans, Pachymatisma johnstonia] and [Halichondria panicea] and anthozoans such as [Sagartia elegans, Urticina felina, Alcyonium digitatum, Corynactis viridis] and dwarf [Metridium senile] generally dominate the area; the anthozoans often appearing to protrude through the sponge layer. There may be dense aggregations of the hydroid [Tubularia] [indivisa], the cup coral [Caryophyllia smithii] and the colonial ascidians [Botrylloides leachi] and [Polyclinum aurantium]. There may be a short crisiid turf, interspersed with [Scrupocellaria reptans]. Encrusting coralline algae may occur on well-illuminated rock faces. The echinoderms [Asterias rubens], [Marthasterias glacialis], [Echinus esculentus], [Antedon bifida] and [Ophiothrix fragilis], the topshell [Calliostona zizphinum] and the calcareous tubeworm [Pomatoceros triqueter] may also be present on the rock face. The crabs [Cancer pagurus] and [Necora puber] may also be recorded. Due to the wave-surged nature and vertical orientation of these biotopes, kelps are rare and certainly never dominate.
