Frogs and Warts
Why it's false
Frogs and toads do not actually give you warts. Warts can only be caused by a human virus. However, the reason why the myth started was because frogs have wartlike bumps behind their ears. These are dangerous and can cause irritation to skin. That is why it is best not to touch these critters.
Frogs and luck
Why it's true and false
The frog has been a symbol of good luck in many cultures throughout the history of the world. In Japan, they believe that frogs descended from a great ancestor who could suck all the mosquitoes out of a whole room in a single breath! However, in other cultures, frogs are looked down upon. Some people associate them as evil incarnations of the devil.
Frogs and Weather
Why it's true
Frogs have been associated with weather throughout the world and in many cultures. It makes sense because they are considered to make a lot of noise before rain storms. For example, some Australian aborigines and Native American groups believed that frogs were the bringers of rain.
Frogs and their skin
Shedding
Frogs are actually known to shed and eat their own skin like most animals. They do this so they do not waste all the nutritious protein found in their skin. This is the ultimate way to recycle all the components they use to produce their skin.
Breathing
When frogs start out as tadpoles, they breathe underwater through internal gills. Normally, frogs breath with their mouths closed. Their throat movements pulls air through the nostrils and to the lungs. Frogs can also breath through their skin, with tiny blood vessels, capillaries, under the outer skin layers.
Drinking
Frogs absorb water directly through their skin in an area known as the 'drinking patch' which is located on their belly and the underside of their thighs.
