Seven snail species hidden in one: Biogeographic diversity in an apparently widespread periwinkle in the Southern Ocean
Aim: The Antarctic Circumpolar Current imparts significant structure to the Southern Ocean biota. The Antarctic Polar Front is a major barrier to dispersal, with separate species (or sometimes intraspecific clades) normally occurring either side of this feature. We examined the biogeographic structu...
