Facts about this animal
The Zambian mole-rat is a rodent of 9-12 cm length and a body-weight of 30-60 g that lives and forages underground, and under natural conditions is rarely, if ever, exposed to light. Its eye is organized as in other rodents and is prominent but minuscule. The animals do not seem to react to light behaviourally or to orient visually.
Zambian mole-rats live in families consisting of a single breeding pair and their non-breeding offspring, who remain with their parents and forage and maintain the burrow system. This eusocial system was first found in the naked mole-rat (Heterocephalus glaber), but whereas in that species the queen monopolizes breeding through behavioural suppression of her daughters, in Zambian mole-rats, both daughters and sons refrain from mutual mating because of incest avoidance based on continued familiarity with each other. They readily initiate courtship when encountering unfamiliar conspecifics, including their own siblings, however, after separation of 16–18 days.
Zambian mole rats feed on roots, tubers, geophytes, herbs and grasses.

Why do zoos keep this animal
Zambian mole rats are of educational interest because of their extreme adaptation to a subterranean lifestyle and their interesting social system. A lot of research has been and is being done on Zambian mole rats kept under ex situ conditions.
