Derived, in part, from: the UK marine biotope classification (Connor et al.

Circalittoral rocky habitats subject to strong wave action or tidal currents and
supporting animal communities which are robust enough to survive in such strong water
movement. The fauna is generally low-lying faunal crusts, cushions and turfs but also
includes communities of the large soft coral Alcyonium digitatum. Included here are
habitats which occur in very strong tidal streams (ECR.BS) in tidal channels (sounds,
sealochs) as well as those found on wave exposed coasts (ECR.EFa, ECR.Alc), as there are
strong similarities in species composition in some cases.
