Fun Facts; Plethodonidae salamanders do not have lungs or gills; they "breath" (take in oxygen) through their skin and this is why they need to be moist all the time,18 to 19 coastal grooves (sometimes 17 or 20). Red-backed salamanders are a very important species throughout their range. They are the most abundant vertebrate and have been shown to range as high as 3000 individuals per hectare. In their range, their numbers exceed all birds and mammals combined and their bio mass exceeds that of birds and equals that of small mammals. This make them an extremely important prey species as well as predator (of invertebrates). Red-backed salamanders are the most prevalent and wide spread of Long Islands salamanders.
