Description

The southern giant pouched rat is a large rodent, with males larger than females. Adult males typically weigh, while females weigh. From their nose to the tip of their tail, these animals are approximately long. They have dark brown to reddish fur on their backs and a pale belly. The tail is bi-colored, brown with white at the distal third of the tail.
Females have small litters, usually between 1-3 young at a time. Males scent mark using cheek and anogenital rubbing, as well as urine, and appear to preferentially mark unfamiliar locations.

Taxonomy

An analysis of cranial head measurements, as well as mitochondrial cytochrome b phylogeny shows C. ansorgei to be distinct from other members of the genus Cricetomys. C. ansorgei may have a largely-undescribed sister species that resides west of the Congo River. Previously, many animals described as Cricetomys gambianus may have instead been C. ansorgei based on this new characterization.

Use by humans

The southern African giant pouched rat is used in tuberculosis detection, and in locating landmines through initiatives by APOPO. It is also popular as bushmeat.
