How many baby Greater white-toothed shrews are in a litter?
A Greater white-toothed shrew (Crocidura russula) usually gives birth to around 4 babies.
Each of those little ones spend around 29 days as a fetus before they are released into the wild. Upon birth, they weight 1 grams (0 lbs) and measure 2.9 cm (0′ 2″). They are a member of the Soricidae family (genus: Crocidura). An adult Greater white-toothed shrew grows up to a size of 6.9 cm (0′ 3″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
The greater white-toothed shrew (Crocidura russula) is a small insectivorous mammal found in Europe and North Africa. It is the most common of the white-toothed shrews. This species is found along the Mediterranean, Netherlands, Belgium, Germany and Portugal; in addition, the Osorio shrew of the Canary island of Gran Canaria, originally described as a separate species (Crocidura osorio), was later discovered to be a population of introduced greater white-toothed shrew. Furthermore, a subspecies of the greater white-toothed shrew, Crocidura russula ibicensis, is found on the Mediterranean island of Ibiza. In April 2008, the greater white-toothed shrew was discovered in Ireland as well. Its preferred habitats are grassland and woodland. It is slightly larger than the lesser white-toothed shrew but otherwise very similar and can often be distinguished only by close inspection of its teeth which are unpigmented.
