The Mexican Spadefoot Toad is found in the southwestern United States and most of central Mexico. Like all spadefoot toads, the Mexican Spadefoot Toad does have keratinized spade-like projections on their hind legs. They use these spades to burrow into the ground. The Mexican Spadefoot Toad spends most of the day underground, coming up at night to hunt and look for mates. For mating, it usually takes place after heavy rains. Breeding periods only last one or two days in ponds and pools that form from the rains. These pools and ponds only last a few weeks. Therefore, the eggs hatch in a few days and it only takes the tadpoles a couple weeks to undergo metamorphosis.
