A local population of the introduced green macroalga Codium fragile ssp. tomentosoides was investigated in Oban in the district of Argyll, western Scotland. Periodic surveys demonstrated that sacoglossan densities (Elysia viridis and Placida dendritica) were unusually high in 1997 and early 1998, slug herbivory noticeably damaged algal thalli, and the local algal population was decimated. These patterns provide indirect evidence of the significance of slug herbivory on the introduced alga.
