Recorded distribution in Britain and Ireland

CMU.SpMeg, and the sub-biotope CMU.SpMeg.Fun are typical of the deep mud habitats of the Scottish sea lochs. The biotope CMU.SpMeg has been recorded in most of the Scottish sea lochs (Howson et al., 1994) and in the Shetland voes (Howson, 1988). It has also been observed in the north-eastern Irish Sea (Hughes & Atkinson, 1997) and in the deep offshore waters of the North Sea (Dyer et al., 1982).
