Glass frogs are beautiful small (2-2.5cm) animals from the tropical rain forests of South and Central America. They are really transparent, you can even see their heart beating. Also the intestines and small bones in their feet and fingers are visible. Glass frogs live high up in the trees, you can only find them down by the water during the breeding season. They deposit their eggs on leafs that are hanging above a water surface of ponds and streams. The male protects the eggs against predators until they hatch. Tadpoles will then fall into the water where they develop further into frogs. The species in the video below, Hyalinobatrachium fleischmanni has a wide distribution range going from Mexico all the way until Ecuador. It is relatively big for a glass frog with a size ranging from 2 to 2,5cm.
