The southern giant pouched rat is widely distributed in mainly tropical regions of southern Africa, notably Zimbabwe, Kenya, Tanzania, Zambia, and the Democratic Republic of Congo.

The southern giant pouched rat is a large rodent, with males larger than females. Adult males typically weigh 1.5 to 2.0 kilograms (3.3 to 4.4 lb), while females weigh 1.2 to 1.6 kilograms (2.6 to 3.5 lb).[citation needed] From their nose to the tip of their tail, these animals are approximately 70 to 80 centimetres (28 to 31 in) 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.

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.

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.
