Survey was carried out to describe the range of sublittoral habitats and species. A specific survey was made on opisthobranch molluscs. Lists of species of flora and fauna are given for the areas investigated. Some work was done on the south Cornwall coast around Mounts Bay. Within the islands the variety of major habitats recorded was not high due to heavy wave action and variety of species was rather low. Records currently considered sensitive have been removed from this dataset.
