The African bullfrog is a voracious carnivore, eating insects and other invertebrates, small rodents, reptiles, small birds, fish, and other amphibians that can fit in their mouths. [5] [9] [10] It is also a cannibalistic species—the male African bullfrog is known for occasionally eating the tadpoles he guards, [11] and juveniles also eat ...
The bullfrogs frequently kill and eat residents' fish and chicks, both of which are important to the islanders. While Indian law prohibits their killing, it is still done, both out of desire to rid the islands of the species and for food (H. tigerinus is a very cheap source of protein). Despite these efforts, the frogs' spread continues.
They are immune to the poison and they secrete it through their skin as a defense mechanism against predators. This poison is so efficient, the native people of the South American Amazon rainforest use the frogs' toxins on their weapons to kill their prey, giving the frogs their nickname the "poison dart frog".

Duke Health is a trial site for a drug that could be the first universal antivenom to treat any kind of snake bite — including North Carolina’s ubiquitous copperhead.
American bullfrogs (Lithobates catesbeianus), also widely distributed, are also thought to be carriers of the disease due to their inherent low susceptibility to B. dendrobatidis infection. [21] [22] The bullfrog often escapes captivity and can establish feral populations where it may introduce the disease to new areas. [8]
