Faunal communities on variable salinity Atlantic infralittoral mixed sediment

Description (English)

Shallow sublittoral mixed sediments in estuarine conditions, often with surface shells or stones, enabling the development of diverse epifaunal communities, e.g. Crepidula fornicata (MB4-242), as well as infaunal communities. This habitat type is therefore often quite species rich, compared with purer sediments.
