Neotenic individuals remain entirely aquatic and can be found hiding amongst coarse gravel or rocks at the bottoms of clear, cool, flowing streams or small springs where invertebrate prey is plentiful. Fully metamorphosized adults often live a subterranean lifestyle, but can be found in moist leaf litter and detritus over muddy ground or seepage areas.
This species of salamander is often neotenic, but sometimes metamorphosizes into adult, terrestrial form.
