Glass frogs are extraordinary!
They have transparent skin (most likely to help with camouflage) that allows you to see the entirety of their intestines. However, glass frogs too are being affected by global warming.
Some of the habitats where glass frogs live are becoming too dry. This is no good for the residents of Central and South America, as it makes it more difficult for species like these to live.
