This check list is mostly based on E. Naylor & A. Brandt (2015) Intertidal Marine Isopods, Synopsis of the British Fauna (New Series), No. 3. The Linnean Society of London, FSC. The list includes a number of sublittoral isopods that may sometimes be encountered in the intertidal zone or in inshore waters but excludes strictly offshore species.
Nomenclature follows the current World List of Marine, Freshwater and Terrestrial Isopod Crustaceans (http://www.marinespecies.org/isopoda/).
