Frogs live on land and in fresh water. Frogs cannot survive in salt water. Frogs hatch as tadpoles (the name for baby amphibians) from eggs from a female frog. The eggs are called spawn. Tadpoles have fins and gills. When they grow up, they lose their tails and gills and have four long legs. Grown frogs can jump far with their legs. They have long tongues that they use to catch bugs.
