This behavior has been observed in which the Arboreal Salamander uses its body to create a controlled and directional fall to minimize injury when climbing trees. This aerial behavior is thought to be the result of generations of salamanders having to adapt to falling from their habitat. [9] A large adult can inflict a painful bite.
Unlike other salamanders, whose larvae are developed in water, the alpine salamander and its subspecies are a fully terrestrial species in life and gestation. [8] They give birth to live young. [9] Alpine salamanders produce toxic compounds from their skin. [8] These compounds may protect them from both predator and microbial threats. [10] [11 ...
Newts, as with salamanders in general and other amphibians, serve as bioindicators because of their thin, sensitive skin and evidence of their presence (or absence) can serve as an indicator of the health of the environment. Most species are highly sensitive to subtle changes in the pH level of the streams and lakes where they live. Because ...
The southern two-lined salamander is a small thin salamander, distinguished by the two lines running down the lateral portion of its body. The salamander is deep-light brown and fairly small, growing up to 6.5–12 cm in length. The species has 14 costal grooves between its limbs. [2]
Male marbled salamanders have also been shown to have a higher survivorship than females. [9] Marbled Salamanders in the northern portions of their range can also go into a state of torpor to survive the cold months. [10] Adults spend most of their time in their burrows or under logs, as is the case with most mole salamanders.
A higher proportion of salamander species than of frogs or caecilians are in one of the at-risk categories established by the IUCN. Salamanders showed a significant diminution in numbers in the last few decades of the 20th century, although no direct link between the fungus and the population decline has yet been found. [83]

Like most woodland salamanders, the Shenandoah salamander eats mites, flies, small beetles, springtails, and other soil invertebrates. [9] No direct observation of predation of the Shenandoah salamander has ever been reported, but potential predators residing within the habitat of the Shenandoah salamander include ring-necked snakes, short-tailed shrews, brown thrashers, and towhees.
