Ruthven's Frog: Allophrynidae
Ruthven's Frogs And People
People rarely see this frog in the wild, although it is actually quite common in the parts of South America where it lives. Scientists find it interesting because they do not know exactly where it fits in the family tree of all frog species. Once they find tadpoles or possibly a fossil of a frog, however, they may learn details that will help them decide if the Ruthven's frog should stay in its own family or should be included in another family, such as the glass frogs.
