Despite lacking specialized climbing structures, a wide range of salamanders are known to climb vegetation, trees, or rocks. Their ability to cling and climb allows these salamanders access to more food resources, to more suitable microclimates, and to escape predators. O'Donnell and Deban (2021) explored what factors contribute to this ability across a wide range of size, morphology, and ecological niches in salamanders. They found that the adhesive nature of their mucus coating was a major factor, but that cling ability also was associated with body mass and the amount of body contact area utilized, which include feet, tail, belly, and ventral surface of their head, to increase cling. The best clingers in their experiments were the small plethodontid salamanders, such as Batrachoseps attenuatus, Desmognathus aeneus, D. ocoee, Eurycea guttolineata, and E. wilderae. However, plethodontid salamanders in general, like large salamander Desmognathus quadramaculatus, were comparable or exceed the cling ability of arboreal and scansorial frogs.
