CR.C.Cv recorded () and expected () distribution in Britain and Ireland (see below)
|Distribution of biotope in Britain and Ireland||Occurs at widely separated locations generally in open coast waters on wave sheltered coasts with moderate tidal flow. Whilst the structural and functional aspects of the biotope are similar across its range, species composition varies.|

Caves and overhanging rock in the circalittoral zone, away from significant influence of strong wave action. This habitat may be colonized by a wide variety of species, with encrusting sponges including some that are seldom seen such as Dercitus bucklandi and Thymosia guernii, anemones Parazoanthus spp. and the cup corals Caryophyllia inornatus, Hoplangia durotrix. In the south-west, Leptopsammia pruvoti may be abundant in restricted areas. (Information taken from the Marine Biotope Classification for Britain and Ireland, Version 97.06: Connor et al., 1997a, b).
The biotopes classification lists the scarlet and gold star coral Balanophyllia regia as characteristic but that coral occurs in shallow (infralittoral) depths and is a feature of overhangs, often exposed to strong wave action, there.
