sell without a permit in the following US states: Arizona, California, Kentucky, Louisiana, New Jersey, North Carolina, Oregon, Vermont, Virginia, Hawaii, Nevada, and Washington state. However, it is legal to own Xenopus laevis in New Brunswick (Canada) and Ohio. Feral colonies of Xenopus laevis exist in South Wales, United Kingdom. In Yunnan, China there is a population of albino clawed frogs in Lake Kunming, along with another invasive: the American bullfrog. Because this population is albino, it suggests that the clawed frogs originated from the pet trade or a laboratory. The African clawed frog may be an important vector and the initial source of Batrachochytrium dendrobatidis, a chytrid fungus that has been implicated in the drastic decline in amphibian populations in many parts of the world. Unlike in many other amphibian species (including the closely related western clawed frog) where this chytrid fungus causes the disease Chytridiomycosis, it does not appear to affect the African clawed frog, making it an effective carrier.
