The Nesomyidae are a family of African rodents in the large and complex superfamily Muroidea. It includes several subfamilies, all of which are native to either continental Africa or to Madagascar. Included in this family are Malagasy rats and mice, climbing mice, African rock mice, swamp mice, pouched rats, and the white-tailed rat.

Characteristics

Nesomyids are small to medium rodents, with the largest being the size of a rat. Physically, they may resemble mice, rats, voles, or hamsters, depending on the species and subfamily. Their diets vary from fairly strict herbivory to nearly pure insectivory, and levels in between. Their habits are similarly variable, with some species climbing trees, and others burrowing in the ground. They give birth to up to four young after a gestation period of around six weeks.[1]

Classification

Many of these animals were once thought to be related to other groups of muroid rodents, but this African-based clade has been proposed and confirmed on the basis of genetic studies. Such alternate arrangement include the pouched rats in the family Muridae, and the white-tailed rat in the family Cricetidae. Likewise, all members of the Nesomyidae are often placed in the family Muridae along with all other members of the Muroidea.

Nesomyids are classified in six subfamilies, 21 genera and 68 species.
