Naked Mole Rat

There are many different kinds of mole rats. The best known is probably the naked mole rat, whose hairless, tubular, wrinkled body makes it appear a bit like a tiny walrus—or perhaps a bratwurst with teeth.

Description
The Naked Mole Rat, native to North Eastern Africa, is one of the most mysterious and unusual mammals on our planet. As it spends its entire life underground in burrows, it is almost completely blind, and finds its way around using its sense of smell and touch-- both of which are exceedingly accute. Naked Mole Rats are able to communicate through pheromones, scent-massages which allow the family group to organise itself. In fact, they act so cohesively together that they live in colonies, like ants or wasps, and are thus regarded (along with their furrier cousin, the Mole Rat) as the only truly eusocial mammals. The Naked Mole Rat, being immune to cancer and most other diseases, has the immunity ability, as well as digging, and colony, meaning any creature with a Naked Mole Rat head only takes up one space in the population cap.
