The Greater White-toothed Shrew (Crocidura russula) is a small shrew found in Europe and North Africa. Its preferred habitats are grassland and woodland. It is slightly larger than the Lesser White-toothed Shrew but otherwise very similar, and can often be distinguished only by close inspection of its teeth.
In April 2008, the Greater White-toothed Shrew was discovered in Ireland. While the introduction of the species will possibly sustain threatened birds of prey, such as the Barn Owl, the non-native mammal could threaten some of the smaller native species, such as the Pygmy Shrew.
