Ceramium sp. and piddocks on eulittoral fossilised peat
|Within Vocab||Marine Habitat Classification for Britain and Ireland Version 97.06|
|Definition||Outcrops of fossilised peat in the eulittoral are soft enough to allow a variety of piddocks (such as Barnea candida and Petricola pholadiformis) to bore into them. The surface of the peat is characterised by a dense algal mat, predominantly Ceramium spp. but also with Ulva spp., Enteromorpha spp. and Polysiphonia spp. Damp areas amongst the algal mat are covered by aggregations of the sand mason worm Lanice conchilega and the fan worm Sabella pavonina. The anemone Sagartia troglodytes and the crabs Carcinus maenas and Cancer pagurus occur in crevices in the peat. Small pools on the peat may contain hydroids, such as Obelia longissima and Kirchenpaueria pinnata, the brown alga Dictyota dichotoma and the prawn Crangon crangon.
