Northern Zigzag Salamander

Description

Occurs in the eastern two-thirds of TN below 2500 ft. Zigzag Salamander, Plethodon dorsalis, was fairly recently split into Northern and Southern Zigzag (P. ventralis) Salamander, which appear identical. A small, dark-colored salamander (2.5 to 3.5 inches in length) with a red or orangish wavy pattern, or “zigzag”, extending from the neck down the back to the base of the tail, where it straightens out. This species also occurs in a brownish-gray color morph without the zigzag. Small white flecks occur on the back and sides, giving a metallic appearance. The belly is gray or black with orange or reddish speckles.

Similar Species: Eastern Red-backed Salamander has a straight-edged dorsal stripe. The Southern Zigzag Salamander is distinguished from identical Northern Zigzag Salamander by its range and genetic analysis.

Habitat: Prefers moist habitats of rocky hillsides, forested slopes, leaf litter, and entrances to caves.

Diet: Small invertebrates, especially spiders and beetles.

Breeding information: Northern Zigzag Salamanders breed terrestrially during the fall and spring. Females lay 3-9 eggs in underground cavities or in cave entrances during the spring and summer. Females remain with the eggs until hatching in the fall.

Status in Tennessee: One of the more abundant salamanders in TN.

Best places to see in Tennessee: Moist, rocky slopes in middle Tennessee, or the  Cumberland Plateau.
