The Life Cycle of a Frog
Diagram of the Frog Life Cycle
| Mom and Dad Frog Decide to Have Baby FrogsThe 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. You know this is happening when you see dad frog hugging mom frog from behind her. The dad frog will lay on top of mom frog and wrap his front legs around her body and he will hug her for several days. This hug is called amplexus.
While mom and dad frog are hugging, mom frog will lay a bunch of eggs for the dad frog to fertilize. Unlike human eggs, frog eggs are fertilized by dad frog when they are outside of the mom frog’s body. This is called spawning and is the very beginning of the frog life cycle. After the mom and dad frog have finished spawning, dad frog leaves, and sometimes the mom frog does, too. Sometimes mom frog will stick around, though, and wait for the baby frogs to hatch so that she can care for them, but this only happens with some breeds of frogs, not all of them.
| The Frog EggsMom 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.
| The Tadpole
When frog eggs hatch they don’t come out as frogs right away, they have to start out as tiny little fish-like creatures called tadpoles. In the beginning 7 days or so of tadpole development, a tadpole will eat the egg yolk that is still left in its gut. The only parts to the baby...
