Life is so hard that the naked mole rat continue their lives as a hive organism with germ-free workers and a single breeding queen.
Naked mole rats can run backwards very fast just as fast as forwards and they have no sense of pain in their skin. Their metabolism is 30 per cent slower than other mammals of their size that living on this earth. Surprisingly, they could hold a record as the longest rodent life that span (28 years) and never get cancer.
The naked mole rat also has another name as the sand puppy or desert mole rat, is a burrowing rodent native to parts of East Africa and is the one and only species currently classified in the genus Heterocephalus.
