Mantidactylus opiparis is a medium-sized frog from the Mantellidae family. It lives only in the central part of Madagascar near mountain streams in rainforests.
Mantidactylus opiparis differs from related frogs by its unique call and adhesive discs on its fingers, which help it cling to slippery rocks. It is important for nature because it eats many insects and serves as food for snakes and birds.
Immature form that undergoes metamorphosis before adulthood.
