Wyoming toad

At the Detroit Zoo
The Detroit Zoo’s breeding program for the federally endangered Wyoming toad was No. 1 on the Association of Zoos and Aquariums (AZA) list of the Top 10 wildlife conservation success stories for 2007.  The annual list recognizes the efforts of AZA-accredited zoos and aquariums to protect wild animals and, in the Zoo’s case, bring them back from the brink of extinction. The toads are not on exhibit but are bred behind the scenes at the award-winning National Amphibian Conservation Center – a leader in amphibian conservation and research – which houses a spectacular diversity of frogs, toads, salamanders, newts and caecilians. 


Its skin is covered in warts and its head has a humped ridge. It comes in various shades of brown, a perfect camouflage against its predators.


Scientific name: Bufo baxteri
Continent: North America
Habitat: Only found in the floodplains of the Laramie Basin in Wyoming
Size: 2 inches long
Weight: 2-3 ounces
Diet: Ants, beetles and other invertebrates
Reproduction: Eggs are laid from mid-May to early June and the larvae usually metamorphose by mid-July.

Conservation Status: IUCN currently lists them as Extinct in the Wild because no self-sustaining population exists in the wild. Although they do exist in the wild, everything in the wild came from captive-breeding programs.




The Wyoming toad relies on its prey to move in order to hunt because of its poor eyesight.
