• Exosphaeroma inornata

  Exosphaeroma inornata is a sphaeromatid isopod originally described by Dow in 1958 from California. The species was later synonymized with E. media George and Stromberg 1968 from San Juan Island, Puget Sound, with differences between original descriptions attributed to author errors or phenotypic variations. It is a wide-ranging intertidal species with documented occurrence from San Diego, California north to San Juan Island, Washington, though a significant distribution gap exists between Humboldt Bay and Puget Sound.
