Littoral surveys on Jersey shores in the Channel Islands (southern English Channel) revealed unexpected spatial variation in local-scale distributions of green macroalgae belonging to Codium species. Traditionally considered a low-shore alga, native C. Vermilara inhabited high and/or mid-shore pools at nine of ten shores surveyed. This alga was frequent on semi-exposed shores. The introduced taxon C. Fragile ssp. tomentosoides was patchily distributed with highest abundances in wave-sheltered areas. Zonation patterns of Codium spp. on Channel Island shores were more complex than those north of the English Channel.
