Damara mole-rat (Cryptomys damarensis). Distributed in semi-arid regions of Botswana, Namibia, South Africa, Zambia, and Zimbabwe; inhabits grasslands, savannas, and scrub with loose soils. Colonies number a dozen to several dozen individuals, sometimes more than 40, and exhibit eusociality with a single breeding pair at the top of the colony. Underground burrow systems are deep with living chambers and storage rooms; bulbs and rhizomes are the main foods, which they store and manage. Breeding occurs once or twice a year; gestation lasts about 78–92 days. Population is stable; conservation status: Least Concern.
