The beautiful transparent Glass Frog

The Glass frog is a beautiful frog species that has a semi-transparent skin

Among the many weird and fascinating amphibians on our planet, very special are the Glass Frogs. This amazing frog family has a transparent skin, allowing you to view inside its small body. They are so transparent that it almost looks as if they melt into the leaves and become one with them. Transparent animals like these frogs are spectacular to see.

Glass frogs live in and among the trees and plants of humid mountain forests in Central and South America. Higher up the mountain the rainforests are called cloud forests because the trees are almost always covered in clouds. Glass frogs are mostly active at night, which makes them very difficult to spot for predators.

During the breeding season they live along rivers and streams where they lay their eggs on leaves that overhang the water. When breeding is over, most glass species go back to live high up in the canopy.

Conservationists are especially interested in these beautiful frogs because they may be good bioindicators. A bioindicator is a species that provides clues about the health of the environment where it lives. As the Earth’s weather changes, some of the rain- and cloud forests where Glass Frogs live are becoming too dry, making life difficult for the frogs, as well as other plants and animals. By watching the glass frogs, scientists can learn what impact global warming has on these forests and the amazing species that inhabit them.

      Hi Tracey, I was also amazed by these transparent frogs. Although there are more transparent animals (mostly invertebrates), it especially suits the green glass frog very well!

    I love these facinating creatures! I am constantly looking up new facts about these amazing amphibians and looking for new and unique images of them. Now I am very interested in different animals and these are different looking, weird but great! At the moment I am working on a small project about unique looking animals and their different ways of living. I am trying to aim it at endangered animals, animals within risk of becoming extinct or animals that could become endangered soon. So far I have a long list of different animals (as there are so many odd looking animals and even more that are endangered)! Here are a small amount of the animals that I have put onto my list:
    Glass frog
    Glass fish
    Blow/puffer fish
    Mexican walking fish
    Long eared jerboa
    Sunny fish etc…
    I was wondering as you seem as if you know a lot about animals (endangered or not) whether you could give me a small list on some endangered animals that I could include. Thanks!

    At the moment at school I am doing a school project on this animal and I have looked at lots of endangered animals. I have mainly looked at the glass frog, glass fish, blow fish, mexican walking fish, long eared jerboa and the sun fish. In the end I decided to go to this website and do the glass frog as they are epic! I am trying to raise awareness to save the glass frog and try to save it. Thanks for giving me lots of great facts for me to add to my leaflet, I am going to include things about its way of living and also things to grab people attention.
    Thanks!
