On earth, there are over 5000 frog species. They are cold-blooded animals. Their body temperature is the same as the air and water temperature. They lay up under the sun to warm up when it is cold, and when it gets too hot, they get into the water.

There were frog fossils found which date back to more than 140 million years ago that dates back to the Jurassic period. Frogs are widely distributed in the whole world, but Antarctica.

They have an unusual hatching habit

For catching prey, the Surinam toad makes itself flat, looking like a pancake. Its whole life is spent in the water. when both sexes mate, the female’s release eggs, and the males catch the fertilized eggs. The eggs are then embedded in a spongy tissue on the females back where they grow. The froglets burst out of the mothers’ back after.
