Iberian shrew juveniles, the fur is also adapted for cold, damp habitats: each guard hair possesses an indentation along its length that helps to prevent water from reaching the body. The skull of "S. granarius" can be used to distinguish it from other species belonging to the European "Sorex araneus" group of shrews. Comparatively, the snout of "S. granarius" is small and flat, the mandible possesses a diminished coronoid process and a narrow angular process, and the temporal fossa of the skull resembles a triangle. The "Sorex araneus" group of European shrews consists of "S. araneus", "S. coronatus", and "S. granarius", with
