Science at its Best

Secondly Nacional Geographic news was found a frog species without lungs. It's true... The frog knownen by Barbourula kalimantanensis, he gets all the oxygen that it needs through its skin... ;-ppp

The frog was found in Indonesia on the island of Borneo during a study lead by David Bickford, a biologist at the National University of Singapore. This species lives in cold, fast-flowing water... They noted that the loss of lungs might be an adaptation to a combination of factors: a higher oxygen environment, the species’s presumed low metabolic rate, severe flattening of their bodies that increases the surface area of their skin, and selection for negative buoyancy—meaning that the frogs would rather sink than float.

All history was describes in the May 6 issue of the journal Current Biology.
