2. Frogs — Did you know that frogs are the best leapers on the planet? They can launch themselves over 20 times their own length! That is like a person jumping over 100 feet! Wow! What about this - how can frogs croak so loud that they can be heard for miles and manage not to blow out their own eardrums? Well, frogs have ears that are actually linked to their lungs. When they hear, not only does their eardrum vibrate, but their lungs do too! This special system protects them from hurting their ears.
