A few new creature are making scientists jump for joy! Experts found the world’s four smallest frog species: Paedophryne amauensis, Paedophryne swiftorum, Paedophryne dekot and Paedophryne verrucosa. The frogs may have big names, but each measure about 0.3 to 0.4 inches long, smaller than an M&M candy. Scientist track these frogs by listening to their calls which can be heard 80 feet away. What a extraordinary finding!
