Naked mole-rats live in dark burrows and have very poor eyesight. However, they can locate and move inside the burrows with ease. How is that so?

1. They have sensitive hairs in the body to navigate inside burrows.
2. Their naked skin is highly tactile which helps navigate inside burrows.
3. Their large teeth chew on underground roots to mark territories inside burrows.
4. Their ears catch high frequency vibrations which help locate inside burrows.
5. Their eyes have night vision to navigate well inside dark burrows.
