Check out this frog. That is one small frog, huh? On a dime, all, daaaamn, what is this enormous metal disk I am on in his tiny high-pitched frog voice. The scientists who discovered this guy couldn't even hear his tiny voice. "It was particularly difficult to locate Paedophryne amauensis," says frog-discover Chris Austin of Louisiana State University, "due to its diminutive size and the males' high pitched insect-like mating call." I bet, man. This frog, Paedophryne amauensis, is 7.7 millimeters long and it is literally the tiniest veterbrate known to human beings. He's all, whatever, though. [Discovery; image via LSU]
