Amphibians who hatch from eggs as tadpoles. As they grow, they lose their gills and tails. They grow legs and breathe using their lungs. 

I watched a frog jump from one rock to another in the pond. 



Fish and tadpoles use this part of the body to breathe in the water

Humans breathe through their noses and fish breathe through their gills.


To come out of an egg

When I go to the county fair, I like to watch baby chicks hatch from the eggs.

A baby frog that has a small round body, no legs, and a long tail. It breathes through gills.

We could see the tadpoles swimming near the side of the pond.
