World’s smallest frog discovered, is smaller than a dime Researchers say they have discovered the world’s smallest frog species. The Paedophryne amauensis is only 7.7 millimetres in length on average and may be the world’s smallest vertebrate, researchers said in a PLoS One journal article published Wednesday.
The frog fits easily on a dime, with room to spare.
The species was discovered in New Guinea, where the same U.S. researchers also found another frog species of only slightly larger size — the Paedophryne swiftorum. Both were found living in leaf litter on the jungle floor.
“This discovery highlights intriguing ecological similarities among the numerous independent origins of diminutive anurans [frogs], suggesting that minute frogs are not mere oddities, but represent a previously unrecognized ecological guild,” the researchers said in the article.
