Natural History

The Relict Leopard Frog is a rare find and were thought to be extinct. Because of this, there is not much that is known about many of their habits. They are active year-round and are most often observed in shallow water along channels or pool margins. They have been found to breed in September, November, and late January through March. Adults most likely eat invertebrates while tadpoles are more herbivorous, consuming algae and plant tissue.

Fun Facts
