crocidurines

Crocidurines are a subfamily of shrews within the family Soricidae. These small, active mammals are found across a wide range of habitats in Africa, Asia, and Europe. They are characterized by their generally drab, uniform coloration, typically shades of brown, grey, or black. Unlike their white-toothed shrew relatives, crocidurines possess dark, often reddish-brown or black teeth. Their diet consists mainly of invertebrates such as insects, worms, and spiders, although some species may also consume small vertebrates. They are known for their high metabolic rates, which necessitates frequent feeding. Crocidurines are generally solitary and territorial, communicating through scent marking and vocalizations. Reproduction typically involves multiple litters per year, with short gestation periods and altricial young. Some species, like the lesser shrew or the Eurasian white-toothed shrew, are widespread and abundant, while others may be more localized or face conservation concerns due to habitat loss. Their ecological role often involves insect population control.
