Pumpkin toadlets look exactly like what their name suggests. Less than half an inch-long, these tiny, orange frogs hop around the sweltering forests along Brazil’s Atlantic coast. But how many species of these frogs are there? The question isn’t just important to biology, but for conservationists seeking to preserve unique rainforest amphibians.
To researchers, pumpkin toadlets belong to the genus Brachycephalus. Determining how many Brachycephalus species exist, however, isn’t easy. As many as 36 have been named, but researchers sometimes disagree on which species are valid or which species a particular population of frogs should be assigned to. Different populations of these frogs look very similar to each other, not to mention that their genetic makeup only varies slightly.
