The Mazatlan Narrow Mouthed Toad was originally thought to be its own species before researchers merged it into the Great Plains Narrowed Mouth Toad (Gastrophryne olivacea). It sat as a subspecies for over 50 years before researchers decided to elevated back to its own species. Not much is known to be different in its life history than the Great Plains Narrowed Mouth Toad and it seems no one has really tried to study it. They spend most of their life underground which also doesn’t help with knowing what they are doing. However, the toads come to the surface to breed. They breed following the heavy spring and summer rains.
The International Union of the Conservation of Nature (IUCN) Red List has not assessed the conservation status of the toad.
