European Natural Information System (EUNIS) habitat classification code: A3.236/B-MIR.SedK.HalXK - Halidrys siliquosa and mixed kelps on tide-swept infralittoral rock with coarse sediment (Davies & Moss, 1998).

The biotope £MIR.XKScrR£ is similar but receives less sediment abrasion than this biotope and is characterised by a mixed kelp canopy, rather than Halidrys siliquosa.
