When they are in their eggs tadpoles are surrounded with a kind of jelly. Tadpoles breathe under water through their gills. While tadpoles are starting to grow their tails start to shrink. When they’re all grown up, they turn into adult frogs. Adult frogs breathe with their lungs. In spring the mother frogs lay their eggs but in winter the frogs start to hibernate. When they’re hibernating, frogs dig through the mud. When they’re in the mud, they breathe through their skin and they don’t eat until the following spring. Then they come out of the hole and start eating.
