4. Mom and Dad Frog Decide to Have Baby Frogs The life cycle of a frog starts when mom and dad frog fall in love and decide to have baby frogs. Okay, nobody really knows if frogs fall in love, but it’s okay to think that they do. Mom and dad frog will mate, either in the water or in a tree, depending on what kind of frogs they are.

5. The Frog Eggs Mom frog will lay a whole bunch of eggs because most of them won’t hatch. Some of the eggs will be eaten by other small animals and birds, and some of them won’t become fertilized. Other eggs might become dried up in the sun or get broken in the water. The eggs that survive will hatch after about 7 to 9 days and begin the frog cycle and start the many life stages of a frog. But they don’t get to be frogs just yet; they have to go through the tadpoles’ life cycle first.

6. Frog is an amphibian -- it can live both in water and on land. In this chapter, you will learn about the life cycle of a frog. T R I V I A Next time you go to a pond or a small lake, observe the edges. At the edge of the pond, you might see frog eggs floating. They look like little balls of almost clear jelly, all clumped together. If you see closely, you will notice a dark speck inside each little ball. The speck grows bigger and starts to take a shape. When a frog egg hatches, a baby frog with a broad face and a long flat tail come out. This baby frog is called a tadpole. It lives in water, and swims around in the pond. As the tadpole grows, two little legs begin to sprout from the back of its body. Soon, two more legs begin to grow in the front. At the same time the tadpole’s tail shrinks and its body grows bigger. It looks more and more like a frog. The frog grows and matures until it is ready to reproduce. A female frog lays about one thousand eggs at a time. But not many of these eggs will hatch into tadpoles because so many other creatures in the pond, such as fish like to eat frog eggs. After the female frog lays the eggs, and a male frog fertilizes them, then the fertilized eggs float in the water like a glob of little jelly balls with dark specks inside. The specks grow bigger and begin to take shape, and the life cycle of the frog continues.
