The genus of Weißzahn- or batting shrews ( Crocidura ) is a mammalian species from the family of shrews (Soricidae). In a broader sense, this name is applied to the subfamily of the Crocidurinae . With almost 200 species it is the most species-rich genus of mammals, three species (the field shrew , the house shrew and the garden shrew ) also live in Central Europe.
features
The fur of these shrews is dense and silky, it is colored brown, gray or black on the upper side, the underside is lighter. The tail is long and, like the back of the body, eyelashed. The claws are short compared to other shrew species, the 28 teeth are colored white. These shrews reach head body lengths of 4 to 18 centimeters with a tail of 4 to 11 centimeters. The weight varies from 3 to 65 grams depending on the species.
distribution and habitat
White-toothed shrews are restricted to the Old World, they are found in Eurasia and Africa , and the greatest biodiversity is in central Africa . They inhabit a variety of habitats, for example forests and grasslands, but also fields and sometimes invade buildings.
Way of life
Like all shrews, they feed mainly on invertebrates (e.g. insects and earthworms ) and are characterized by a high metabolic rate. So they consume almost their own body weight in food every day. They are very fertile, two to ten young animals are born once or several times a year after a gestation period of around three to four weeks.
threat
Particularly some species with a small range are threatened. Directly threatened with extinction ( critically endangered are), according to IUCN C. dhofarensis , C. Harenna , C. negrina , C. thomensis and C. wimmeri and additionally there is the on the Christmas Island endemic type C. trichura that may already be extinct. 15 species are endangered and 20 are endangered ( vulnerable ), but precise data are lacking for some species.
The species
A total of almost 200 species are distinguished. Three species live in Central Europe:
- the field shrew ( Crocidura leucodon ),
- the house shrew ( Crocidura russula ) as well
- the garden shrew ( Crocidura suaveolens )
Four other species, C. sicula (in Sicily ), C. ichnusae (in Sardinia ), C. canariensis (in the Canary Islands ) and C. zimmermanni (in Crete ) are native to southern Europe. Most of the species live in Africa (around a hundred species are restricted to central or southern Africa) or in Southeast Asia (where there are several endemic species in the Philippines , Indonesia, and the Andaman and Nicobar Islands ).
