The Blanco River Springs salamander has adapted to its aquatic lifestyle by becoming lungless (4). Instead of having lungs to breathe like most salamanders, it instead retains external gills throughout its life (3). Like other lungless salamanders, it is also able to breathe through its moist skin (4).
Like other aquatic salamanders, the Blanco River Springs salamander mates and lays its eggs underwater. Closely related species are thought to deposit their eggs in gravel (2).
The feeding habits of the Blanco River Springs salamander have not been fully researched, but it is likely that this species mainly predates small, aquatic invertebrates (2).
