North Carolina is home to the most salamander species in the United States, a whopping 63 species! Now, thanks to researchers, the number moves up to 64! The southeastern United States, especially the Appalachian Mountain, is the salamander capitol of the world.
This discovery was 50 years in the making. An unusual salamander species was brought to the North Carolina Museum of Natural Sciences. Originally, it was thought to be a weird Southern Two-lined Salamander (Eurycea cirrigera). More specimens were collected and curator Alvin Braswell thought it could be a new species. Sadly, he was too busy to pursue the research.
In comes Bryan Stuart, research curator of herpetology, who join the museum in 2008. Braswell told him of the salamander and wanted him to research it. Stuart was able to use next generation sequencer to determine that the species was new. He formally described the species as the Carolina Sandhills Salamander (Eurycea arenicola). The salamander is found near the seepages, springs and streams of the Sandhills of North Carolina. The Carolina Sandhills Salamander is red to orange in color. They don’t have a the dark band on its side like the Southern Two-lined Salamander do. These salamanders are pretty small ranging from 2.2 – 3.5 inches (56. -89.1 mm) from snout to tail.
