Ornate horned frogs have voracious appetites, but they are not built for chasing down prey. They bury themselves in leaves or loose soil and pounce on small animals that blunder by. When harassed by a human or other large animal, these fearless frogs lunge and snap their huge jaws. Like little green bulldogs, they bite and hang on until pried loose.
The Waxy Monkey Leaf Frog Phyllomedusa sauvagii has adapted to meet the demands of life in the trees. It does not need to return to the ground during the mating season, rather it lays its eggs down the middle of a leaf before folding the leaf, sandwiching the eggs inside. Its nest is attached to a branch suspended over a stream so that hatching tadpoles drop into the water.
