Faunal communities of Atlantic circalittoral coarse sediment

Description (English)

Tide-swept circalittoral coarse sands, gravel and shingle generally in depths of over 15-20m. This habitat may be found in tidal channels of marine inlets, along exposed coasts and offshore. This habitat, as with shallower coarse sediments, may be characterised by robust infaunal polychaetes, mobile crustacea and bivalves. Certain species of sea cucumber (e.g. Neopentadactyla ) may also be prevalent in these areas along with the lancelet Branchiostoma lanceolatum .
