Once its prey has been located it moves towards the prey using a series of hops to sneak up on its meal. Using its tongue and strong bite from the jaw smaller prey are consumed and engulphed using its mouth. Larger prey that are not able to fit in the American Bullfrogs mouth have been observed to be assisted using its hands, with larger prey observed to be asphyxiated after a successful catch as a defense mechanism. This behavior mimics other forms of feeding from other frogs, most notably a wood frog .
