Scientists do not know much about what these frogs do, but they eat small animals without bones, for example insects. Scientists have seen some of these species lay eggs in small pools of water in holes in trees, in bamboo, or in karst rocks. The female lays 4–20 eggs just above the water. After about one to two weeks they hatch into tadpoles that fall into the water. They become small frogs after a few months or a year.
