6. Although Paedophryne amauensis is small, that doesn’t mean that they are weak. One of these incredible little frogs can jump up to 30 times the length of their body. If I do my math correctly, that means they can leap close to 10 feet.

8. Paedophryne amauensis was discovered when Christopher Austin and Eric Rittmeyer were recording nocturnal sounds in Papua New Guinea and heard a new animal. They didn’t realize how small the animal was and scooped up leaves near the location of the noise to see what was hiding under them. What they didn’t realize what that the small frogs were living among the leaves, where it’s wet enough to sustain them.
