Darwin’s frog (Rhinoderma darwinii) is a rhinodermatid frog native to the forest streams of Chile and Argentina. It  is named after Charles Darwin who discovered it in Chile during his world voyage on the HMS Beagle.

The most striking feature is the way the tadpoles are raised—inside the vocal sac of the male.
