****d Mole Rat
The ****d mole rat (Heterocephalus glaber), also known as the sand
puppy, or desert mole rat is a burrowing rodent native to parts of
East Africa and the only species currently classified in genus
Heterocephalus. It is notable for its eusocial lifestyle, nearly
unique among mammals, and for a highly unusual set of physical traits
that enables it to thrive in a harsh, underground environment;
including a lack of pain sensation in its skin, and a nearly cold-
blooded metabolism. - Wikipedia
