The first known species of frog that breathes without lungs has been found on the Indonesian island of Borneo. The frog receives oxygen through its skin.
Named the Barbourula kalimantanensis, this rare species was first described in 1978 and again 15 years later. Those specimens were deemed to valuable to dissect. Biologist David Bickford performed partial dissections when he encountered the species on a recent trip to Borneo.
