Antenna 2 flagellum not reaching the length of the peduncle (except possibly in large males which have tufts of setae on the flagellum ); usually less than 1/5 of the body Brusca (1984) regarded Idotea a cosmopolitan genus, but which is absent from the warm and tropic seas in both the Pacific and the Atlantic oceans. Most of the Idotea species are endemic and restricted to shorelines in Europe, North America or Asia. Only two species, Idotea balthica and Idotea metallica, have a Description. A dorso-ventrally flattened isopod crustacean with an elongated oblong, oval body.

Males range in length from 1-3 cm while females range from 1-1.8 cm. Idotea densities were significantly higher and mean body size significantly smaller on Corallina than the other algal species. Isopods were significantly larger on Fucus . There was no significant difference in base colour frequencies between shores but there was a positive association between the brown base colour and Corallina and the green colour and Fucus . The two species of isopods, Idotea baltica (Pallas) and Idotea emarginata (Fabricius), co-occur frequently near Helgoland, North Sea, occupying different ecological niches. Respiration rates and kinetic properties of citrate synthase (CS) were compared in these species in order to identify possible … Small specimens of Idotea, taken in hauls of surf plankton at Robin Hood's Bay, were chiefly I. baltica (Colman & Segrove 1955). In the Isle of Man Moore (1937) records the species as commonly trawled in Port Erin Bay and Bay Fine (Fig.
