Yes No No Opinion
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
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.
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.
