Naked Mole-Rat

“The naked mole-rat (Heterocephalus glaber), also known as the sand puppy or desert mole rat, is a burrowing rodent closely related to the blesmols, native to parts of East Africa, and is the only species currently classified in the genus Heterocephalus. The genus is classified as being in the family Bathyergidae or in its own family, Heterocephalidae. The naked mole-rat, the Damaraland mole-rat, and Mechow’s mole-rat are eusocial mammals, the highest classification of sociality. It has a highly unusual set of physical traits that enable it to thrive in an otherwise harsh underground environment; it is the only mammalian thermoconformer, almost entirely ectothermic (cold-blooded) in how it regulates body temperature.”
