    Paedophryne

    A genus home to the smallest frogs and as a matter-of-fact, smallest vertebrates on earth

    Native to Papua New Guinea, these narrow-mouthed frogs are also known as “child toads” or “child frogs”. Not surprising, given their size. At a measly 7mm or 0.27 inches in length, Paedophryne amanuensis, a member of the genus, might be the smallest vertebrate on earth – a group that includes mammals, fish, birds, and amphibians.

    Due to apparent reasons, these frogs are hard to spot, but can easily be heard due to their high-pitched calls, which sound like crickets. As of now, the genus contains seven species in total, ranging in size from that of a fruit fly to the size of your toenail.
