They have long, slender bodies and long tails. They have two color phases. In the "redback" phase they have a gray or black body with a straight-edged red or orange stripe down the back, extending from the neck to the tail. When they are in the "leadback" phase they lack the red stripe, and have a purely black or grey back instead. Their bellies are a mottled white and gray in both phases, creating a salt and pepper pattern. Red-backed salamanders have 16-19 grooves on their sides.
These salamanders are found in deciduous forests throughout their range. They live in fallen leaves as well as under rocks, logs, or in small burrows.
Red-backed salamanders are active during both day and night, depending on weather conditions. They are relatively solitary and defend small territories in which they feed. Red-backed salamanders lay eggs that develop directly into small salamanders. They do not have an aquatic larval stage, unlike other salamanders and most amphibians.
They could be affected by high levels of acid in the soil caused by human-induced factors like acid rain.
