Characteristics: The most common salamander is the redback salamander. It has two different color phases. The "redback" phase consists of a gray or black body with a red or orange stripe down the back, extending from the neck onto the tail. The "leadback" phase lacks the red stripe, with a purely black or gray back instead. Its belly is a mottled white and gray in both phases, creating a salt and pepper pattern. The redback salamander has 16 to 19 costal grooves, no circular constriction at the base of its tail, five toes on its hind feet, and grows to about five inches. These physical characteristics help to distinguish the redback salamander from other salamanders similar in appearance.
Habitat: Redback salamanders are terrestrial and live in deciduous forests. They are found in the leaf litter on the ground as well as under rocks, logs, or in small burrows. They need to live near water because they do not have lungs and require moist skin for respiration.
