Chirp! Is that a stranger?

This is a naked mole rat. It lives underground. It cannot see well. Its ears are on the inside.

Chirp. Squeak. It talks to other rats in its colony. Rats from another family do not make the same sounds.

All the rats in each group sound like their queen. God gave the rats a way to know when a stranger comes into their colony. The strange rat does not sound the same as they do! Genesis 2:19 says, “So out of the ground the Lord God formed every beast of the field.”
