Well, they are going to be featured in my next book “Amphibians”. Other than that, their extremely compact, puffy shape gives them a small surface area-to-volume ratio, which is a key adaptation to prevent moisture loss in the dry desert.

They are found in a narrow, 6.21 mile coastal strip of sand dunes, and their existence is threatened by mining and habitat loss.

Depends on the species. Some breeders do sell rain frogs, but they aren’t cheap. They can go for upwards of $200, plus shipping.

The males call during mating season, till they get paired up with a mate. Otherwise, they call when threatened.

Added. Also added that these frogs skip the tadpole phase and are born as froglets. Thanks for the suggestion.
