Mexican burrowing toad

A Mexican burrowing toad.

Scientific name: Rhinophrynus dorsalis

Like the magical Mooncalf, this mysterious toad spends most of its time hidden in its underground burrow. Scientists suspect it emerges only once a year, after heavy rainstorms when it comes out to breed. Researchers often find Mexican burrowing toads by following the sound of their wailing mating calls.

Fantastic feature: Spade-like growths on its back feet help this toad tunnel underground

Where to find them: In Central America, calling out for a mate after rainstorms
