Radde's shrew is found around the Caucasus. The color of its upper molars varies among specimens, and tests have recorded contact between individuals.
Juveniles have brown fur on the back and sides, with a slightly lighter belly. Adults have darker fur and weaker brown tints. The tail is uniformly dark on all sides.
In tests at the Caucasus Reserve, shrews in different age and sex combinations touched and clustered together.
