The Southern Hognosed snake is the most critically threatened throughout its range. Habitat loss is the main culprit with collection for the pet trade and introduced predators such as fire ants and domestic animals contributing to its decline . Southern Hognosed snakes vary little in color and pattern throughout their limited range and there are few reports of captive breeding projects producing color morphs.
