Naked Mole Rat（裸鼢鼠）

The naked Mole Rat is native to some parts of East Africa. They spend most of their lives underground and are well adapted to this underground environment. With most of their skin exposed, they lack sweat glands and subcutaneous fat. These ugly guys use their giant, protruding teeth and jaws to dig extensive holes in the ground. The underground parts of plants serve as their food. They live in colonies like bees and have one queen who is responsible for all reproduction.
