European Union Natural Information System (EUNIS) classification: A3.B1/B-CR.Cv - Communities of circalittoral caves and overhangs (Davies & Moss, 1998). The biotope classification (Connor et al 1997a) appears rather mixed-up regarding the components of the researched biotope and the very similar SCR.Scup. The assessment of sensitivity is for both.
