Conservation status is Endangered

Common Name: Amargosa Toad
Scientific Name: Anaxyrus nelsoni
Family: Bufonidae – True Toad family
Locations: United States – Nevada
Size: 5 inches (127 mm)

The Amargosa Toad is found in the Oasis Valley along the Amargosa River, hence the name. Its species epithet –  nelsoni is in honor of Edward William Nelson (May 8, 1855 – May 19, 1934) , an American naturalist. The toad has an extremely small range, so it is considered to be endangered by the International Union for the Conservation of Nature (IUCN) redlist but is not on the United States Endangered Species list. Locals are working to help restore the populations of the toads to avoid it being listed as an endangered species. The cause of the declines of the toads are due to habitat loss and the introduction of invasive species such as American Bullfrogs (Lithobates catesbeianus) and crayfish. Interesting fact about the Amargosa Toad is that the males do not call to attract females for breeding.
