Heterocephalus glaber, commonly known as the naked mole-rat, is a small, burrowing rodent native to East Africa. It is notable for its hairless, wrinkled skin and large front teeth, which it uses for digging. Naked mole-rats live in colonies, similar to social insects, and have a unique social structure with a single breeding female, known as the queen, and several non-breeding workers. These rodents are remarkable for their longevity and resistance to cancer, living up to 30 years in captivity. They are also ectothermic, meaning they rely on their environment to regulate body temperature, and can survive in low-oxygen conditions, making them well-adapted to their underground habitats.
