Uncharismatic Fact of the Day
Like all amphibians, frogs have the remarkable ability to absorb oxygen through their skin. However, because this isn't the most efficient way to breathe, most species of frog grow a set of lungs when they become adults. The Bornean flat-headed frog is one notable exception: the species has no lungs at all, and respites entirely through its skin! This trait is shared only with a few salamanders and caecilians, a group of subterranian amphibians.
