Desmognathus is a genus of lungless salamanders in the family Plethodontidae known as dusky salamanders.[1][2] They range throughout the eastern United States as far west as Texas, and north to southeastern Canada.[1]
Characteristics
Species of the genus Desmognathus have a unique jaw-opening mechanism where the lower jaw is stationary and the skull swings open.[3] There are additional stalked condyles, an atlanto-mandibular ligament, along with other skeletal and musculature features that have evolved to accompany this type of jaw-opening mechanism.[3] Additionally, they are known to exhibit maternal care by brooding over their eggs.[3]
