The term "Heterocephalus" refers to a genus of rodents known as naked mole-rats. These unique animals are native to East Africa and are notable for their hairless bodies, which help them adapt to their underground habitats. Naked mole-rats live in large colonies and exhibit a social structure similar to that of honeybees, with a single breeding female and several non-breeding workers. Heterocephalus is also known for its remarkable longevity and resistance to cancer, making it a subject of scientific research. Their ability to thrive in low-oxygen environments and their unique social behaviors contribute to their status as an intriguing species in the study of mammalian biology.
