2 “Anyone seen my eggs………I think I left them in this pond?”

3 Growth stages The fertilized eggs of a frog are called frog spawn.The blobs inside the eggs are called embryos and they are protected in a bag of jelly.

4 The eggs are laid in water and after a week or so they hatch into tadpole.They swim around and breath through gills and will grow very quickly.

5 After about 7 weeks the tadpole grows hind legs and then front legs and it will soon breath through lungs rather than gills.

6 The frog’s tail begins to get shorter but the legs continue to grow and at 14 weeks the frog is then an froglet and can leave the water.

7 Frog Life Cycle Frog Spawn [eggs] Fully grown Froglet. Tadpoles 2 weeks old. After 7 weeks the tadpole grows front and hind legs.
