Mid and upper shore wave-sheltered muddy fine sand or sandy mud with narrow-leafed eel grass [Zostera noltii] at an abundance of frequent or above. It should be noted that the presence of [Z. noltii] as scattered fronds does not change what is otherwise a muddy sand biotope. Exactly what determines the distribution of [Z. noltii] is not entirely clear. It is often found in small lagoons and pools, remaining permanently submerged, and on sediment shores where the muddiness of the sediment retains water and stops the roots from drying out. An anoxic layer is usually present below 5 cm sediment depth. The infaunal community is characterised by the polychaetes [Scoloplos armiger, Pygospio elegans] and [Arenicola marina], oligochaetes, the spire shell [Hydrobia ulvae], and the bivalves [Cerastoderma edule] and [Macoma balthica]. The green algae [Enteromorpha] spp. may be present on the sediment surface. The cha...
