American bullfrog

The American bullfrog (Lithobates catesbeianus) is a large frog native to eastern North America. Its deep call and human-assisted spread have made it familiar in many regions worldwide.

Anura: The amphibian order comprising frogs and toads, which lack tails as adults and typically have long hind limbs. The American bullfrog is a member of this order.
Ambush predation: A hunting strategy in which a predator waits concealed before striking nearby prey. Bullfrogs often remain still before lunging at prey within reach.
Frog legs: A food product consisting of the hind limbs of frogs, eaten in several culinary traditions. Bullfrogs are harvested and farmed for their large edible hind legs.
Invasive species: A non-native organism that spreads and causes ecological, economic, or human-health harm. Bullfrogs are treated as invasive where their spread damages local ecosystems.
California bullfrog invasion: The establishment and spread of introduced American bullfrogs across parts of California. California populations illustrate the species' effects on native aquatic wildlife.
Tadpole: The aquatic larval stage of a frog or toad, usually bearing a tail and gills. Bullfrogs spend an extended period developing as aquatic larvae.
Metamorphosis: A biological transformation in which an animal changes form during development. Bullfrog tadpoles transform into air-breathing, four-limbed adults.
Aquaculture: The farming of aquatic organisms in controlled freshwater or marine environments. Bullfrog farming is one form of raising aquatic animals for food.
Predation: An interaction in which one organism captures and consumes another. Introduced bullfrogs eat native amphibians and many other animals.
Bullfrogs in Europe: Introduced American bullfrog populations found in parts of Europe. European populations have prompted monitoring and efforts to prevent further spread.
