The American bullfrog (Lithobates catesbeianus), often simply known as the bullfrog in Canada and the United States, is a large true frog native to eastern North America. It typically inhabits large permanent water bodies such as swamps , ponds , and lakes .
[21] [22] The bullfrog often escapes captivity and can establish feral populations where it may introduce the disease to new areas. [8] It has also been shown that B. dendrobatidis can survive and grow in moist soil and on bird feathers, suggesting that B. dendrobatidis may also be spread in the environment by birds and transportation of soils ...
Because amphibians generally have a two-staged life cycle consisting of both aquatic and terrestrial phases, they are sensitive to both terrestrial and aquatic environmental effects. Because their skins are highly permeable, they may be more susceptible to toxins in the environment than other organisms such as birds or mammals. [9]
The exception to this is where the American bullfrog is not native and has been introduced. In these ecosystems, American bullfrogs can decimate local amphibian populations, upset ecosystem balance, and have negative impacts on other species of wildlife as well.
Lithobates, commonly known as the bullfrogs, is a genus of true frogs, of the family Ranidae. [1] The name is derived from litho- (stone) and the Greek bates ( βάτης , one that treads), meaning one that treads on rock, or rock climber.
Once released into the aquatic environment, zoospores travel less than 2 cm (0.8 in) within 24 hours before they encyst. [21] The limited range of B. dendrobatidis zoospores suggest some unknown mechanism exists by which they transmit from one host to the next, [21] which can involve the pet trade, and especially the American bullfrog.

Shankar says that Bullfrog was born into existence through his interactions with three people: Kanye West, Marvel Studios founder David Maisel, and legendary comics creator Todd McFarlane.
The cane toad (Rhinella marina) has been known to survive 24 years in captivity, and the American bullfrog (Rana catesbeiana) 14 years. [171] Frogs from temperate climates hibernate during the winter, and four species are known to be able to withstand freezing during this time, including the wood frog (Rana sylvatica). [172]
