Lemur leaf frogs, also called lemur tree frogs, are small, critically endangered frogs native to Central America. Their bright, yellow-green skin helps them camouflage among leaves during the day. At night, when these nocturnal frogs are most active, their skin turns brown.
They move slowly, walking hand over hand, and rarely jump unless escaping from danger
