6. Purple Frog

Located in the Western Ghats of India, this funny-looking creature has been recently discovered. Unlike other members of its species, this one spends his life underground and only comes out into the world for the special mating season.

This is exactly why it’s been so difficult to find him: purple frogs are only found on the surface for a couple of weeks – and they surely do hide well. Research shows that this is the only surviving species of an amphibians group that evolved 130 million years ago!
