The North Cotentin Peninsula (Normandy, France) presents a mosaic of substrates (from gravel to fine sand) favorable to the development of diversified marine benthic communities, so far, never described outside the Rade of Cherbourg. A total of 28 stations was sampled in winter 2017 and 2018, along a North Cotentin coasts, to complete the 30 stations already studied into the Rade de Cherbourg from 2012 to 2015 for a total number of 61 stations. Hierarchical Ascendant Classification and Multidimensional Scaling ordination on the 61 stations allows the identification of eight benthic assemblages corresponding to six EUNIS habitats: 1) Amphipholis squamata and Apseudopsis latreillii in mixed sediment; 2) Spio decorata with or without Apseudopsis latreillii in fine sand; 3) Melinna palmata ... view more»
