The Great Basin Spadefoot Toad is found in the western United States and southwestern Canada. They live primarily in arid, desert regions where rain is hard to come by, but they have adaptations to overcome these hostiles environments. The Great Basin Spadefoot Toads are explosive breeder. Once the spring rain falls, the males migrate to ponds and start calling. After mating, the eggs hatch in 2-4 days. These tadpoles can be herbivorous or carnivorous, depending on the locality. The tadpoles take over a month to fully undergo metamorphosis.
Like all Spadefoot Toads, the Great Basin Spadefoot Toad is great at burrowing. They have powerful hind legs that have keratonized sheaths on their rear feet. This helps them to burrow deep in the ground to protect themselves from their arid environment.
