Poison Dart Frogs

In a world where CO2 emissions don't decrease, temperatures have risen and parts of the Amazon rainforests and other rainforests have become savannahs. To adapt, poison dart frogs lose their colorful skin and become fully green to camouflage with their environment. They sport powerful back legs for burrowing and hiding during the day and hunting small insects for food at night when temperatures are cooler. Because of their diet change, the poison dart frogs have lost their toxicity. Their skin would be drier to maintain moisture. Their toes would be shorter to reduce the chance of injury. Their toes would be hard like claws to help them burrow. The way they moved would stay the same.
