SHURE Department of Biology, Emory University, Atlanta, Georgia 30322 Abstract. Larvae hatch with fully functioning limbs and external gills and spend about 2 weeks terrestrially near the female before taking to the water where they will overwinter. Younger individuals often have an irregular light coloured stripe that that runs down the back and onto the tail while older individuals tend to be uniformly dark brown or black. Salamandra fuscus Green, 1818, J. Acad. A variety of vertebral centrum morphologies have evolved within early tetrapods which range from multipartite centra consisting of intercentra and pleurocentra in stem‐tetrapods, temnospondyls, seymouriamorphs, and anthracosaurs up to monospondylous centra in lepospondyls. Their back legs are larger and stronger then their front legs, and their tail is partially keeled. The salamanders usually use rocks, logs, or other debris for shelter. Younger individuals have a greater range in color from olive to chestnut to dark tan. A row of white spots, or "portholes," runs along each side, posterior to front legs.The tail is slightly flattened.This species is variable in color but is generally dark brown to black, sometimes with a lighter patch running down the back.

Larvae possess a few pairs of yellowish spots bordered with a dark, wavy lateral line that goes along the back.
