Waxy Monkey Frog
Phyllomedusa sauvagii

Most frogs like cool, moist places. Waxy monkey frogs like it hot. They seal in moisture by giving themselves a rubdown with a waxy substance secreted through skin glands. Climbing to an exposed perch, they draw in their arms and legs and sleep in the sun. They awaken and hunt at night when the air temperature and the rate of water loss are lower.
