The Mexican burrowing toad, Rhinophrynus dorsalis, is a species that spends much of its life below ground. The range of this species extends from extreme southern Texas south to Costa Rica. They are found in dry habitat with strong rainy seasons that form temporary ponds. They breed in these ponds. The frogs have large spades on their feet for digging called metatarsal tubercles. This individual was photographed in 2007.
