"Chameleons may hibernate or aestivate in times of extreme cold or heat. In these conditions, chameleons slow their body down and wait for the temperature to warm up or for the rainy season to come. This is an extremely powerful adaptation that some chameleons have evolved that allow them to surivive in times of extreme hardship. Some species, such as Parson's Chameleon, have been known to dig burrows in the ground and remain their for many months until the weather becomes less severe. "
