The Life Cycle of a Frog • The Life Cycle of a frog begins with five stages Of Metamorphosis. • The Egg (surrounded by a clear layer that absorbs in water and as time goes by thickens protecting the yoke of the egg).
The Metamorphosis of a Frog • The egg begins to hatch in 4-5 days. • The larvae emerges forming into a Tadpole. • Tadpoles have jaws that allow, gills, and tiny eyes that grows larger as the tadpole enlarges. • Parts of a Tadpole: • Eye • Muscular tail • Spout
Life Cycle of a Frog • Parts of a Tadpole
Life Cycle of a Frog • The Tadpole slowly begins to change into an Adult Tadpole after 5 weeks and begins to have even more frog like characteristics. • Forming hind legs • Horny lips • “Elbows” begin to sprout out. • The tails becomes smaller. • And the lungs becomes almost fully developed; preparing the frog to live on land or water.
Life Cycle of a Frog • Fun Facts: Frogs live on every continent except Antarctica. • Frogs are Amphibians. (Cold-blooded animals)
Life Cycle of a Frog • The next stage is a Froglet. • The adult tadpoles legs are even stronger. • The tail becomes much shorter. • The lungs are almost fully functioning. • The frogs mouth widens. • The frog looses its jaws and after 11 full weeks The froglet becomes an adult frog.
