The Naked Mole Rat is a rodent. Africa is the native home of the Naked Mole Rat. These rats form colonies of 20 to 300 individuals. Each colony has its own queen, workers and guards. They dig a tunnel in the desert and grasslands where the colony can live. This tunnel system may stretch for up to 5 km. These tunnels have a number of chambers. One is for storing food, another for going to the toilet and one which acts as a nursery. The Naked Mole Rat lacks fur on its body. Its body is covered with wrinkled skin.
