Anaxyrus baxteri

At the Detroit Zoo
The Detroit Zoological Society’s (DZS’s) breeding program for this federally endangered animal was No. 1 on the Association of Zoos & Aquariums’ (AZA’s) list of the Top 10 wildlife conservation success stories for 2007. Since 2001, the DZS has released more than 9,460 Wyoming toads into the wild as tadpoles, toadlets and adults. The breeding population is maintained in special bio-secure rooms behind the scenes of the amphibian center. The Wyoming toad can be seen 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.

The Wyoming toad’s skin is various shades of brown – a perfect camouflage against their predators – and are covered in warts. Their heads have humped ridges. Native to southeast Wyoming, they are typically active at night and spend the day burrowed in wetland areas.

Fun Facts

  • When hunting, the Wyoming toads rely on their prey to move because of their poor eyesight.

  • The Wyoming toads ward off predators by secreting poison from their necks, either killing the predator or giving them a very upset stomach.
