Frog Facts and the Secret of Its Life Cycle — A Nature Picture Book
What makes a frog so amazing?
The frog, the singer of the pond, is an animal that shows off an amazing life cycle, growing from an egg into a tadpole and then into a frog.
Nature and science facts about frogs
Frogs also absorb oxygen through their skin (skin breathing), so their skin must always stay moist. Their life cycle has four stages — egg → tadpole (plant eater) → metamorphosis (hind legs → front legs → tail absorbed) → frog (insect eater) — and the change is truly dramatic. A male's vocal sac amplifies his call, and with eyes that bulge on top of his head he can watch above the water even while submerged. Tree frogs cling to slippery surfaces with the sticky pads on their toes.
What Tangobook's «Frog» covers
Tangobook's «Frog» warmly shows the life cycle — egg → tadpole → metamorphosis as legs appear → becoming a frog — and the frog singing with its vocal sac.
Great things to observe together
Point out the four life-cycle stages, skin breathing (moist skin), the vocal sac, and the bulging eyes. Talking together about "How does a tadpole turn into a frog?" is a wonderful way to spark curiosity.
Parent guide — how to nurture curiosity
In spring, watch tadpoles and follow the metamorphosis as their legs grow over a few days (then return them where you found them). Listening to frog calls together and talking about "the song the males are singing" makes it even more fun.
Frequently Asked Questions (FAQ)
Q. How does a tadpole become a frog?
A. It grows hind legs, then front legs, and its tail is absorbed — a process called "metamorphosis" — until it becomes a frog.
Q. Why is a frog's skin moist?
A. Because frogs also absorb oxygen through their skin (skin breathing). That's why it always needs to stay damp.
Q. How can we observe frogs at home?
A. In spring, watch a tadpole's metamorphosis (then return it), and listen to frog calls together.
