Researchers have confirmed the first case of complete lunglessness in a frog, according to a report in the April 8th issue of Current Biology. The aquatic frog Barbourula kalimantanensis apparently gets all the oxygen it needs through its skin. Previously known from only two specimens, two new populations of the aquatic frog were found by the team during a recent expedition to Indonesian Borneo. The researchers said that further studies of this remarkable frog may be hampered by the species' rarity and endangerment. They therefore strongly encourage conservation of the frogs' remaining habitats.
