Vole, Arvicola terrestris
Water voles are the dominant
herbivorous rodents in non-arid areas. They are frequent on the
densely vegetated banks of rivers and ditches where the currents
are slow. Their noses are blunter, their eyes and ears smaller,
and their legs and tail shorter than those of rats and mice.
Water voles have very high
crowned, rootless cheek teeth; adapted to chewing tough
vegetation, including grass. They swim frequently and dive, but
have no specific adaptations, such as webbed feet, for this. Fur
brushes close off the diastema when the incisors are used for
digging tunnels in which they live.
