LR.FLR.Rkp.H recorded () and expected () distribution in Britain and Ireland (see below)
|Distribution of biotope in Britain and Ireland||LR.H has not been recorded in Ireland. In Scotland, it has only been recorded at Devil's Thrashing Floor, Dumfries & Galloway. On the south Devon coast it is found near Brixham. On the west coasts it has been recorded near Port Talbot in Wales and at Duddon Sands and St Bees Head in Cumbria. It has also been recorded on the north coast of Norfolk and near Blackwater Estuary in Essex.|

Shallow pools on mixed cobbles, pebbles, gravel and sand may be colonized by hydroids (Obelia longissima and Kirchenpaueria pinnata), ephemeral green algae (Ulva sp.) and the winkle Littorina littorea. Within these pools, patches of sand may be occupied by the lugworm Arenicola marina and sand mason worms Lanice conchilega. These pools are often associated with mussel beds (SLR.MytX), with Mytilus edulis also present in the pools. Barnacles (Semibalanus balanoides and Elminius modestus) and the keel worm Pomatoceros triqueter may be attached to shells and small stones.
