Rio Grande Leopard Frog (Lithobates berlandieri) lives in freshwater wetlands across Southwestern United States, Northeastern Mexico. Its conservation status is Least Concern.
Fascinating facts about the Rio Grande Leopard Frog
- At just 2.2 to 4.5 inches (5.6 to 11.4 cm) long, Rio Grande leopard frogs pack powerful, web-footed legs into a body no bigger than a school ruler, letting them sprint across muddy banks and dive into streams in a heartbeat. Their angular noses and long limbs let them burrow when the desert heat spikes, while the webbing gives them a swimming burst. This compact design lets the species thrive in arid landscapes where water is scarce, turning every permanent pool into a safe haven for survival.
- Rio Grande leopard frogs live from sea level up to 701.4 m (2,301 ft) and can be found in water as shallow as.9 m (2.95 ft), showing a tolerance for both high-altitude streams and low-lying ponds. This elevation span lets them occupy desert foothills, grasslands, and even suburban drainage ditches.
- Introduced populations of Rio Grande leopard frogs are expanding south into Baja California and have been linked to declines of the native lowland leopard frog, showing how a common species can become an ecological disruptor. Their ability to colonize new water bodies, combined with a diet that includes insects, tadpoles, and even small vertebrates, lets them outcompete locals for food and habitat, highlighting the need for careful management of amphibian introductions.
- Male Rio Grande leopard frogs can be heard rattling their mating call from a quarter mile away, and in warm U.S. habitats the trill can travel up to a mile, turning night-time wetlands into a chorus arena.
- In warm Mexican climates Rio Grande leopard frogs can breed year-round, but in the United States they peak in spring and fall, with females reaching sexual maturity at 2 to 3.5 years old.
