Discovered as recently as 2003, this living fossil has been described by researchers as a "bloated doughnut with stubby legs and a pointy snout." Looking at this portly purple creature, it's hard to disagree with that assessment. Even more bizarre, its cry sounds like that of a chicken.

 

Though found in India, its closest living relatives can only be found on the Seychelles islands, meaning these frogs have been around for at least 100 million years, when India, Madagascar and Seychelles were connected as a single land mass.
