Fun Facts
1. Frogs "drink" water through their skin instead of their mouth. Frogs don't lap up water with their tongues like dogs or cats. Instead, they absorb all the moisture and oxygen they need directly through a special patch on their belly and thighs called the drinking patch!
2. Frogs swallow their food by using their eyeballs. Because frogs cannot chew, they swallow bugs whole! When a frog catches a meal, it pulls its large eyeballs down into the roof of its mouth, which acts like a biological plunger to push the food straight down its throat.
3. Some frogs can leap up to 20 times their own body length. That is the human equivalent of jumping across an entire basketball court in a single leap! Their leg tendons stretch like powerful rubber bands, storing elastic energy before releasing it for explosive jumps.
4. Wood frogs freeze solid in winter and come back to life in spring. To survive freezing northern winters, the North American wood frog produces a natural antifreeze made of glucose. Its heart completely stops beating and it stops breathing, but when warm spring sunshine arrives, the frog thaws out and hops away completely unharmed!
5. A group of frogs is called an "army." While a group of birds is a flock and fish travel in schools, a collection of frogs is officially known as an army! (A group of toads, on the other hand, is called a knot.)
6. Frogs undergo an incredible metamorphosis. Frogs begin life as swimming, fish-like tadpoles with gills and long tails. Over several weeks, they grow legs, absorb their tails, build lungs, and transform into air-breathing, land-hopping adult frogs!
7. Frogs shed their skin every week and eat it. As a frog grows, its outer skin becomes tight. It performs a little dance to stretch and pull the old skin off over its head like a sweater, then immediately eats the skin to recycle valuable nutrients!
