Frogs reproduce through eggs, which they lay in the water. These eggs hatch into tadpoles that later grow into adult frogs.Know More
There is also a species of tree frog that uses nests that are built into the water so that the tadpoles are born directly in the water. A large group of frog eggs are called frog spawn because they have a gooey, slimy material connecting them together. The frog uses the gooey material to help the eggs reach the surface of the water because the material floats. Female frogs lay between 10,000 and 20,000 eggs.
Once the egg has hatched into a tadpole, then the tadpole has to go through the process of metamorphosis, which turns it into an adult frog. The exact length it takes for metamorphosis to complete depends on the frog species. Most frogs will need several weeks up to a year for the metamorphosis process. Some frogs need more than a year.
The lifespan of a frog is typically 7 to 9 years, but frogs can easily be eaten by predators such as lizards, birds and snakes. Frogs eat insects, fish, mice and even birds depending on what the frog species can fit into its mouth.Learn more in Frogs
