Venezuela: Mt Roraima – Roraima Black Frogs
Most animals on top of Mount Roraima are endemic and found nowhere else on earth. And if you watched National Geographic, you’d be familiar with peculiar black frogs that inhabit this inhospitable plateau. There are two species here – Roraima Black Toad (Anomaloglossus roraima) and Roraima Black Frog (Oreophrynella quelchii), the latter being much smaller then the former. They are completely black with yellow underbelly and very hard to spot as they blend perfectly against the black rock environment. Both species are very rare, making them perhaps the rarest frogs on the planet by sheer numbers on the wild.
