Map icon Distribution of biotope in Britain and Ireland The MERMAID database (JNCC, 1999) shows two records of MCR.Sspi from northeast England and Hiscock (1979) records a community that probably corresponds to this biotope from the Gower peninsula, Wales. The biotope most likely also occurs in the Solway Firth (K. Hiscock, own observations). The most recent (2003) version of the biotopes classification records the biotope (as CR.MCR.CSAB.Sspi) as recorded from the Lleyn Peninsula, Lundy Island (including the wreck of the MV Robert) and the north-east and south coast of England.

For a full description of this biotope including characterizing species, distribution, survey information and references visit JNCC

Bedrock in moderately exposed, slightly tide-swept conditions with high turbidity with an almost entire crust of Sabellaria spinulosa tubes; few other species present. Ciona celata, Alcyonium digitatum and Hypoglossum hypoglossoides present in NE England, very extensive Mytilus edulis in South Wales (Gower). The fauna attached to the Sabellaria crust in many cases seem to reflect the biotopes on nearby rock.
