A frog’s reproductive system is quite different from our own. For starters frogs don’t lay eggs like we do. Instead they release their eggs into the water where they are fertilized by the male frog. This process is known as external fertilization.
Frogs can lay a lot of eggs at once. For example a female African frog can lay up to 12000 eggs at a time!
Frogs typically lay their eggs in water because that is where their tadpoles will develop. But some frogs lay their eggs on land. The female lays her eggs in a moist place and then covers them with a layer of foam. This foam protects the eggs from drying out and from predators.
When the tadpoles hatch they usually fall into the water where they begin their life as aquatic creatures. But if the eggs are laid on land the tadpoles will have to make their way to water on their own.
Frogs are not the only animals that lay their eggs in water. Many fish reptiles and insects do the same thing. Some animals like birds lay their eggs on land.
So how many eggs does a frog lay? It depends on the species of frog but it can be anywhere from a few dozen to a few thousand!
