American Bullfrog
Lithobates catesbeianusAlso known as Bullfrog, North American Bullfrog
American bullfrogs are the largest true frogs in North America, recognizable by their deep, resonant bellows that mimic the sound of a roaring bull. These highly adaptable amphibians are voracious generalist predators, consuming almost any creature they can overpower and swallow, including insects, fish, mice, and other frogs. While native to eastern North America, they have become highly successful and ecologically disruptive invaders in western regions and other continents.

LC
Safe to observe at a normal distance.
- Listen for calls: Listen for their deep, low-pitched 'jug-o-rum' bellows during warm summer nights.
- Approach quietly: Walk softly along shorelines to spot them before they leap into the water with a loud splash.
- Do not relocate: Avoid moving them to new ponds, as they easily spread deadly amphibian diseases.
