A frog that has no lungs and breathes through its skin has been found in a remote part of Indonesia, a discovery that researchers this week said could provide insight into what drives evolution in certain species.

The aquatic frog Barbourula kalimantanensis was found on Borneo in 2007, researchers said Thursday in the journal Current Biology.

The species is the first frog known to science without lungs and joins a short list of amphibians with this unusual trait, including a few species of salamanders and a wormlike creature known as a caecilian.
