Interesting Information• Small frog, reaching 2.5 inches in length• Bright green• Diet – crickets, moths, flies, etc.• Big round ears on the sides of their head

– Some frogs make so much noise that they can be heard for miles!– They have special ears that are connected to their lungs which keeps the frogs from hurting themselves with their noisy calls!

Click on the frog to hear their noisy calls.

How can you tell if a frog doesn't have ears?

You yell "Free Flies" and he doesn't come.

Super Skin:•They drink and breathe through it•Frogs shed their skin to keep it healthy

•This looks pretty nasty. They twist and turn to stretch themselves out of their old skin.•Finally, the frog pulls the skin off over their head, like a sweater, and then (this is gross) the frog EATS IT!

Do frogs have teeth?

Yes, most frogs have a ridge of very small cone teeth

around the upper edge of the jaw

Life Cycle

1st Stage

Frogs lay many eggs.

Most eggs are foundin calm water.

The eggs usually hatchIn about 6 – 21 days.

2nd Stage

7 to 10 days after the tadpole has hatched, it will begin to swim around and feed on algae. Some even

school like fish.

The gills disappear.Tadpoles get tiny teeth.

3rd Stage

After about 6 to 9 weeks,

tiny legs sprout.

The tadpole may now eat dead insects

and even plants.

After about 9 weeks, the tadpole looks morelike a teeny frog with a really long tail.

4th Stage

The frog loses it’s tail. Between 12 to

16 weeks, depending on water and food

supply, the frog has completed the

full growth cycleknown as

metamorphosis.
