The Smallest Frogs are Found in New Guinea

The smallest frogs have been found in the southeastern New Guinea. The frogs are just third of an inch in length and due to the dark brown color they are almost unnoticed among leaf litter and moss of the rainforest floor. In the report made on December 12, Fred Kraus, a zoologist at the Bishop Museum in Honolulu, has announced about two newfound species of the world smallest frogs: Paedophryne dekot and Paedophryne verrucosa. The newfound frog species are also announced to be the smallest known tetrapods (non-fish vertebrates). Due to their small sizes, limbs of the frogs are so small that they are unable to climb the trees; they live among leaf litter and feed on small invertebrates.

Female frogs are slightly smaller than males and they may  carry only two eggs at the time due to their small body. The name” dekot” is derived from the word for “very small” in the local language, Daga, while “verrucosa” was named from the Latin for “full of warts,” due to its distinctively lumpy skin. In 2002, the zoologist Kraus has already discovered two frog species (about 10 and 11 milimeter in length) in the same region which were also recognized as smallest frogs. The scientist confirmed that miniaturization occurs in many frog genera around the world, but those 4 smallest frog species found in the region of New Guinea make him to expect that there might be even more miniature species of frogs in the tropics.
