Centrolene – Giant glass frogs
This crystal-like frog is giant only compared to its nano-sized family members
Contrary to their name, the skin on their backs is generally a brilliant green, and their intestines and heart are exposed through their underbelly.
These not quite “giant” amphibians are 19-24mm (0.74-0.94 inch) long and weigh only 0.7-0.8g (0.024-0.028 oz). They prefer to live near bodies of water. Like other glass frogs, the giant glass frogs are nocturnal, spending their days hidden behind leaves and among trees.
Habitat loss from deforestation and human activity severely threatens their populations because of their arboreal nature.
