Communities of Arctic infralittoral coarse sediment

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 , cumacean crustacea and venerid bivalves. Habitats with the lancelet Branchiostoma lanceolatum may also occur.
