Rhinodermatidae

Rhinodermatidae, called Darwin's frogs, mouth-breeding frogs, and mouth-brooding frogs in English, is a small group of frogs that live in forests in Chile and Argentina.

These frogs are different from other frogs because they are the most basal living frogs in the big group Hyloidea. They became different from other frogs long ago, in the Late Cretaceous. The two genus groups, Rhinoderma and Insuetophrynus, became different from each other during the Paleocene. All three species in the family are now in danger of dying out because of habitat destruction, other animals from far away, and the fungal disease chytridomycosis. The Chile Darwin's frog (Rhinoderma rufum), may already be dead.

Genera
There are two genera, or genuses, in this group:
 Insuetophrynus Barrio, 1970 (1 species)
 Rhinoderma Duméril and Bibron, 1841 (2 species)
