Naked Mole Rat (Heterocephalus glaber)

Naked mole rat has the lengthiest lifespan among all rodents in the world. They have wrinkly skin that's either pink or grayish-pink. They also have short, broad heads, giant incisors, and strong jaw muscles. A naked mole rat can weigh between 1 to 1.5 ounces and have a length of 3 inches. 

You'll find this hairless animal in Kenya, Somalia, Ethiopia, Djibouti, and other countries in Eastern Africa. A naked mole rat can barely see because it has tiny eyes. Also, it can not regulate its body temperature. It maintains its body temperature by huddling with other rats in the colony. 

Although naked mole rats look hairless, they are not. They have sensory whiskers on their tail and faces. The rats also have hairy toes, which help them sweep away soil from their digging activities. Another attribute of the weird animals is their social structure. Naked mole rats have an eusocial system that's unusual for mammals. 

They live in large colonies, with only one female rat performing the breeding while other rats form the workforce. They refer to the breeding female as the queen.
