Alien eyes of amphibians
Those unnerving, almost alien eyes of reptiles seem to pierce your soul. These eyes hold history - you can see how different species have evolved over millions of years. Professional wildlife photographer Daniel Heuclin travels the world and takes pictures of various tropical frogs and lizards that stare right into his lens.
Daniel was amazed by the diversity of species he encountered. This is his favorite photo.
