The greater white-toothed shrew (Crocidura russula) is a small insectivorous mammal[3] found in Europe and North Africa.

This species is found along the Mediterranean, Netherlands, Belgium, Ireland, Germany and Portugal;[4] in addition, the Osorio shrew of the Canary island of Gran Canaria, originally described as a separate species (Crocidura osorio), was later discovered to be a population of introduced greater white-toothed shrew.

[5] Furthermore, a subspecies of the greater white-toothed shrew, Crocidura russula ibicensis, is found on the Mediterranean island of Ibiza.

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 which are unpigmented.

[3] The greater white-toothed shrew is preyed upon by several animals; owls (such as Tyto alba), snakes, and small carnivorous mammals such as weasels and genets are the main predators of C.

[6] In order to avoid predation, the greater white-toothed shrews can be found under cover of vegetation or leaf litter when active.

C. russula possess a primitive form of echolocation where they produce a high pitched twittering call to interpret their environment.

[12] The greater white-toothed shrew typically experiences one breeding season in its entire lifetime, whereby fertilization occurs right after parturition.
