This video says about itself:
An intimate glimpse at North America’s Eastern Hellbender, an ancient salamander that lives as much in myth as in reality…. and in many waters, myths are all that remain of these sentinel stream-dwellers.

Meet the Hellbender
By: David Mizejewski
No, it’s not one of Satan’s minions or a CGI monster. It’s a type of salamander native to the streams and rivers of eastern North America. Despite its demonic-sounding name, this spectacular amphibian is completely harmless to people. Yet the species is rapidly declining due to human activity such as deforestation, erosion and chemical runoff into our streams–which is the real horror story.
Watch this video put out by the Forest Service and partners about one of North America’s most fascinating and little-known wild animals. …
The southern Appalachian Mountains are home to 10 percent of global salamander diversity. But current predictions indicate that 70 to 85 percent of this habitat will become unsuitable for salamanders by 2080 due to rising temperatures caused by climate change. Scientists shows that this extinction risk might be overestimated, because previous research largely ignored the salamanders’ abilities to acclimate. Researchers now project that plasticity reduces extinction risk by up to 72 percent: here.
