Miniaturized frogs form a fascinating but poorly understood group of amphibians. They have been exceptionally prone to taxonomic underestimation because when frogs evolve small body size they start to look remarkably similar – so it is easy to underestimate how diverse they really are.
As part of my Ph.D., I have been studying frogs and reptiles on Madagascar, an island in the Indian Ocean that’s a little larger than mainland France. It has more than 350 frog species, giving it possibly the highest frog diversity per square kilometer of any country in the world. And many of these frogs are very small.
