Blotched tiger salamander adults range from olive to brown to black with yellow blotches or stripes.  As many of these detrimental effects have irreversibly damaged hellbender populations, it is important to conserve the remaining populations through protecting habitats and—perhaps in places where the species was once endemic and has been extirpated—by augmenting numbers through reintroduction. These three groups were shown to be isolated, and are considered to most likely be "diverging on different evolutionary paths". Some salamanders even breathe through their skin! This hellbender subspecies inhabits the White River and Spring River systems in southern Missouri and northern Arkansas, and its population has declined an estimated 75% since the 1980s, with only about 590 individuals remaining in the wild.
