Living Without Lungs…
Do you think this is cute?? 
I think it is cute!.. haha.. but you are actually looking at a very rare species of frog. The frog, Barbourula kalimantanensis, is so rare that the scientific community once cannot take a risk of dissecting it for study. Can you believe that?..
Moving on.. According to David Wake, a biologist and expert in amphibian evolution at the University of California, Berkeley, the frog is so rare that we know almost nothing about its biology. the frog was accidentally discovered to have no lungs when David Bickford, a biologist at the National University of Singapore, and other scientists found the species in a clear,cold-water stream on the island of Borneo in indonesia and did routine dissections to the frogs.
The frogs respire and get all their oxygen through their skin. The flat morphology of the frog is an adaptation to have a greater skin surface area that is exposed to getting oxygen. Also, the lunglessness were adaptations to the fast moving and high-oxygen water of the stream. Coz it is known that lungs cause a body to float and get carried away in fast flowing water.
Well, i am always astonished by nature, specially with the limited knowledge that we have in life under the deep sea. but i am very much happy to browse through national geographic a few moments ago.. hehe

Rally?! That type of frog doesn’t have a lungs? It’s amazing!
and base on the article, I can really therefore conclude that there is really nothing constant but change. Everything changes. Everything evolves just like the frog..
