Mammalia Crocidura russula, commonly known as the Greater White-Toothed Shrew, is a small mammal species found throughout Europe, including the Comunidad Valenciana. This shrew is part of the Soricidae family and is often noted for its distinct white teeth, which differentiates it from other shrew species.

Below are some key characteristics of the Mammalia Crocidura russula:

• Appearance: The Greater White-Toothed Shrew has a relatively small body, typically measuring between 5 to 9 cm in length, with a tail that adds another 3 to 5 cm. It has a dense and soft fur, usually grey-brown on the back and lighter on the belly.
• Habitat: This shrew prefers a variety of habitats, including woodlands, grasslands, gardens, and cultivated areas. It is adaptable, often found near human settlements in Comunidad Valenciana.
