A Frog's Life
A frog starts off as an egg. After a short time
it has grown into a fully grown frog. Scroll down to see the stages that
through and much more.....
Stages of Frog Development
||The female lays eggs in the spring. A group of fertilized eggs is called spawn.|
|They feed on the remaining yolk which is actually in its gut. Their gills, mouth and tail have poorly developed. They begin to swim and feed on algae.|
|A layer of skin grows over their gills. Little teeth begin to appear. A coiled gut starts to develop This helps them to digest food.|
||Their legs begin to grow and their head is more distinct. They start to eat insects and bulge in their daily diet. Arms begin to grow, elbow first.|
|It now looks more like a frog, but still has a stubby tail.|
|They are now fully developed and spending most of their life
out of the water eating a carnivorous diet. Most frogs live between
4 - 15 years.
By doing this project I have learned a lot about the stages of a frog's development. I still can't believe how a little egg can grow into a fully developed frog in only 20 weeks.
