Overview

Distribution

Range Description

This species appears to range from South Africa and Swaziland northwards into Central Africa and East Africa. The northern limits of the distribution are difficult to define as Mus minutoides appears to form an unresolved species complex with the similar Mus musculoides, and the possible distribution of these taxa between Tanzania, southern Sudan in the north and northern Congo in the west is especially unclear. Typical examples of Mus minutoides have been recorded up to 2,400 m asl (Sinner and Chimimba 2005).

Habitat and Ecology
Typical examples of this species have been recorded in Southern Africa from fynbos habitats, savanna, grassland, rocky habitats, vlei and riverine associations, recently burnt grassland, fallow land and suburban areas (though they rarely enter buildings) (Skinner and Chimimba 2005).

Justification
Listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a number of protected areas, has a tolerance of a degree of habitat modification, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

African pygmy mouse

The African pygmy mouse (Mus minutoides) is one of the smallest rodents. It is widespread within sub-Saharan Africa, and is kept as a pet in other parts of the world. Like the common house mouse, it is a member of the enormous superfamily Muroidea, which includes about 1000 different species.

Grey to brick-red overall, it is pale on the underside and has small but prominent triangular ears. Adults are between 30 and 80 mm (1.2 and 3.1 in) long, with a 20 to 40 mm (0.79 to 1.57 in) tail, and weigh from 3 to 12 g (0.11 to 0.42 oz).

African pygmy mice reach breeding age at about 6 to 8 weeks. Pregnancy lasts for around 20 days and the litter of about 3 young is born blind and hairless. Their eyes open after 2 weeks, and weaning is complete after 4 weeks. The lifespan is about 2 years, although individual specimens have been reported to live over 4 years in captivity.

The African pygmy mouse has a number of unique traits. It stacks pebbles in front of its burrow. Overnight the pebbles gather dew and in the morning the pygmy mouse drinks the dew on the pebbles. After that it retires back to its den. Its method of sex determination has also been found to differ from most mammals[2] in that rearrangements of the X chromosome have led to many XY individuals actually being female.

They live in colonies or in pairs in grass close to water and are excellent climbers. They prefer social interaction, and when kept as a pet they can not be left alone.[3] As pets, they cannot be handled due to the risk of inadvertently causing internal damage due to their small size. They have quite simple care needs[4] and are active during both day and night, making them an interesting exotic pet to own.
