Bullfrogs do not have a special diet and will most often eat almost anything that moves and that they can swallow. Invertebrates, small vertebrates, birds, reptiles, fish, turtles, and other frogs are all common prey of the bullfrog. There are very few things the bullfrog cannot eat, thanks to its unique mouth and tongue. The bullfrog's teeth are located in the roof of its mouth, which allows it to trap prey. The long, muscular tongue of the bullfrog can effortlessly flip large prey into its mouth in milliseconds, where the prey is then chomped upon with the frog's sharp teeth.
Bullfrogs are territorial and work hard to protect their space.
Loud calls, physical displays, chases, attacks and wrestling maneuvers are all tactics used by the bullfrog to claim, keep, and protect its territory. Female frogs are most often attracted to males who live in territories that provide the most food. The bullfrog has no natural predators, thanks in part to the toxic secretions its skin produces when touched, and animals that manage to capture the bullfrog often release them due to the unpleasant taste. Coupled with the strength of its long legs, the bullfrog very often never concerns himself with danger. The most important sense to a frog is hearing.
