Hylodes heyeri is a small frog of the Hylodidae family. It lives on rocks near fast forest streams in Brazil and uses leg movements for communication.
Hylodes heyeri differs from other frogs by using visual signals with its legs in noisy streams. It is important for nature as an insect hunter and an indicator of the purity of forest streams.
Immature form that undergoes metamorphosis before adulthood.
