Anaxyrus baxteri, commonly known as the Wyoming toad, is a small, critically endangered amphibian native to the Laramie Basin, Wyoming. It thrives in wetland habitats but has faced severe population declines due to habitat loss, disease, and environmental changes. Notably, it possesses distinct dark spots across its olive skin.

Anaxyrus baxteri, commonly known as the Wyoming toad, is native to the Laramie Basin in Albany County, Wyoming, USA. Historically, it was found in greater abundance within the floodplain and surrounding areas of the Laramie River.

The Wyoming toad inhabits semi-arid regions characterized by high-altitude shortgrass prairie ecosystems. It is primarily found in wetland areas, including ponds, lakes, and marshes, where there is permanent or semi-permanent water. The climate of its native region features cold winters and warm summers, with low precipitation levels.

This species is adapted to living in moist, grassy areas near water bodies, where it can find its primary food sources, such as insects and other small invertebrates. The toad is nocturnal and relies on the presence of water for breeding, laying its eggs in shallow water where the tadpoles can develop.
