We just learned about the big bird called the Ostrich.
The naked mole rat is a rat that lives mostly underground and has almost no hair.
Their families are like bees or ants, where they have one queen who is in charge of having babies,
and a bunch of workers rats who do all the work to take care of her.

The naked mole rat's skin is interesting because they feel very little pain!
