Frogs
Frogs are amphibians because they start their frog life cycle as eggs in the water and then turn into tadpoles, which have gills and also live in the water. It isn’t until a tadpole turns into a frog that it can live outside of the water, but it will still need to get in the water to drink and to cool off. 

Frogs don’t actually drink water with their mouths; they drink it through their skin. A frog’s skin absorbs water when it is in the water so its body gets all of the hydration that it needs that way and the frog doesn’t need to drink with its mouth. 

Frogs are cold blooded. That means that the body temperature of a frog is the same on the inside as it is on the outside. That is why frogs need to be near water so that they can jump in and cool off on hot days. 

Frogs hibernate in the wintertime. 

When frogs hibernate their bones sort of grow a layer, like a tree does. When you look inside a frog’s bone you will be able to see rings and tell how old the frog is by counting the rings. 

Frog fossils have been found all over the world except in Antarctica, probably because it is too cold all year round there for frogs to live. Some of the fossils that have been found are as old as dinosaurs! 

A group of fish is called a school, but a group of frogs is called an army. Do you think that is why army colors are green? A group of people is called a group. 

Not all frogs are green. There are hundreds of species of frogs and each one looks different. Some frogs are red and some are yellow and some are brown. All of the different species of frogs have different patterns on their skin, too. 

The male frog is the only one who can croak, and every frog species makes its own unique sound and some are not even croaks. Some frogs whistle and some chirp like a bird. 

Frogs have teeth on the upper edge of the jaw which are referred to as Maxillary Teeth. The funny thing is, they don't use these teeth to chew their food; they are used to hold the food in place before they swallow it whole!

Frogs take between 12 to 16 weeks to go from a tadpole to their full grown state.

Frogs have a special kind of ears called tympanum that connect to their lungs. When they hear sounds, not only do their ears vibrate, but so do their lungs. One way to tell a male frog from a female frog is by looking at its ears. The ears can be found right behind the frog’s eyes. If the ears are as big as the eyes, then the frog is a boy. If the ears are smaller than the frog’s eyes, then the frog is a girl.
When a frog swallows a meal, his eyes will close and his eyes will actually drop into his throat forcing the food down into his belly.

Frogs hind legs are so strong they are capable of jumping up to twenty times their own body length in a single leap. They are one of the best leapers on the planet.

A frog won’t turn into a prince, no matter how many times you kiss him!

Frogs and Weather
Frogs have been associated with weather in a lot of ancient cultures. I guess this really makes a lot of sense if you consider that they tend to make a lot of noise before rain storms.
• Some Australian aborigines and Native American groups believed that frogs were the bringers of rain.
• In India, frogs were believed to personify thunder in the sky. Even the word for "frog" also meant "cloud" in Sanskrit!
In China, they see the "TOAD", not the "man" of the moon. The toad is also considered "one of the five poisons of yin." They say that eclipses happen when the "toad in the moon" tries to swallow the moon itself. 

Frogs and Luck
Sometimes, cultures associated frogs with good and bad fortune.
• In Japan, frogs are the symbols of Good Luck. One myth I read dealt with the idea that bullfrogs are descended from a great ancestor who could suck all the mosquitoes out of a whole room in a single breath!
• Some myths are less favoring to frogs and toads. Some folklorists* have claimed that "If the first frog that you see in the spring is sitting on dry ground, it signifies that during the same year you will shed as many tears as the frog would require to swim away in." If, on the other hand, the first frog of spring jumps into the water, you'll experience misfortune all year! However, if the springs' first "hop-toad" come jumping in your direction, you will have many friends; if it jumps away from you, you will lose some.

Some less enlightened people associate frogs, and Toads in particular, as evil incarnations of demons or devils! 

Frogs and Warts
Some say that you get warts from touching frogs and toads.
• You get warts from human viruses, not from frogs and toads!
Frogs have slimy skin to stay moist when it is dry, and toads have bumpy skin to help camouflage them in their habitat. Some frogs and toads have paratoidal glands which secrete poisons as protection which can cause skin irritations and may be poisonous to some species of animals, but warts have nothing at all to do with the frogs themselves!
