Naked mole rats explained

The nest of a naked mole rat is really not a comfortable place. The network of tunnels under the East African grassland is baking hot by day, freezing at night and almost airless. Life is so harsh that the naked mole rat lives as a hive organism with sterile workers and a single breeding queen. Naked mole rats can run backwards just as fast as forwards and have no sense of pain in their skin. Their metabolism is 30 per cent slower than other mammals of their size. Surprisingly, they have the longest rodent life span (28 years) and never get cancer.
