Distribution of habitat SS.SCS.ICS  Infralittoral coarse sediment
Distribution of habitat SS.SCS.ICS Infralittoral coarse sediment, based on records on the UK Marine Recorder database and EUSeaMap. Red dots represent records on which the biotope is based. Blue dots show other certain records, black dots show records tentatively assigned to this biotope. Yellow areas show level 2 and 3 sublittoral and deep-sea habitats prediced by EUSeaMap within UK waters.

Biotope description

Moderately exposed habitats with coarse sand, gravelly sand, shingle and gravel in the infralittoral, are subject to disturbance by tidal steams and wave action. Such habitats found on the open coast or in tide-swept marine inlets are characterised by a robust fauna of infaunal polychaetes such as Chaetozone setosa and Lanice conchilega, cumacean crustacea such as Iphinoe trispinosa and Diastylis bradyi, and venerid bivalves.
