Additional information

This biotope has been recorded from 4-98 m on mixed muddy gravel or sand, coarse sands, muddy maerl, and bedrock in areas with weak to strong tidal streams and wave exposed to extremely wave sheltered habitats (Connor et al., 1997; JNCC, 1999; Hall-Spencer & Moore, 2000b). It is probable that the Limaria hians carpet does not occur in shallow depths in wave exposed locations. It occurs at high densities in the Creag Gobhainn area of Loch Fyne (Hall-Spencer & Moore, 2000b) and Moross Channel, Mulroy Bay, Ireland (Minchin, 1995), and is very common in Loch Sunart (Howson, 1996).
