The Holbrook's Southern Dusky Salamander is endemic to the southeastern United States. Thriving in swampy areas with tannic waters near ponds, streams, or river flood plains, these creatures follow a largely nocturnal lifestyle. 

These lungless salamanders have stout bodies, relatively larger back legs, and a row of white spots lining each side of their bodies. Their color varies, ranging from dark brown to black, often accompanied by white-flecked undersides and lighter patches running down their backs. 

Since they look so similar to Northern and Spotted Duskies, you can only tell them apart by where they live.
