Descriptive notes. Head-body 169-9-178-7 mm (males) and 155-2-163 mm (females), tail 23-6-24-4 mm (males) and 21-5-22-5 mm (females); weight 119-8-210-2 g (males) and 113-6-169-4 g (females). The Damara Mole-rat is medium-sized, with short legs, cylindrical body, short tail, and vibrissae on tail and feet. Dorsal pelage is dark brown to black; large head has white head spot. Chromosomal complement is 2n = 74 or 78, FN = 92.
Habitat. Open sandy soils in semiarid thornscrub, savanna, and grassland areas.
Food and Feeding. The Damara Mole-rat is herbivorous and eats geophytes, tubers, and bulbs; it does not drink standing water.
Breeding. Breeding of the Damara Mole-rat is aseasonal. Gestation is 78-92 days;litter size averages three young (range 1-6), with up to three litters per year. Sex ratio is skewed toward males.
Activity patterns. The Damara Mole-rat burrows and digs with upper incisors. It is most active after rainfall and has a circadian rhythm.
Movements, Home range and Social organization. Non-reproductive and unrelated Damara Mole-rats in a colony disperse. Home range averages 1-3 ha. Colonies of Damara Mole-rats are eusocial, with a single breeding female and 1-2 breeding males, overlapping generations, and non-reproductive individuals. Offspring are cared for cooperatively, and non-reproductive individuals forage, defend burrow systems, and care of young. Reproductive female suppresses ovulation of other females. There is widespread multiple paternity and unrelated immigrants in colony; colony size averages eleven individuals (range 2-14); and sex ratio is male-biased.
Status and Conservation. Classified as Least Concern on The IUCN Red List.
