World's Smallest Frogs Tinier Than a Penny


Two small frogs found in southeastern New Guinea are said to be the world's smallest, measuring about 0.4 inches or 8 to 9 millimeters in length. They belong to a group that has small fingers and so they are not expert climbers.

Instead, the frogs, which are smaller than a penny, are excellent leaf litter dwellers.

The two species, Paedophryne dekot and Paedophryne verrucosa, are also the world's smallest tetrapods. Tetrapods are four-limbed animals that have backbones. They include amphibians, reptiles and mammals to name a few.

The two frog species were discovered through field work from researcher Fred Kraus from Bishop Museum in Honolulu, HI. The study was published in the journal ZooKeys.
