The arboreal salamander (Aneides lugubris) is a species of climbing salamander. [3] An insectivore , it is native to California and Baja California , [ 4 ] where it is primarily associated with oak and sycamore woodlands, [ 5 ] and thick chaparral .
In the lungless salamanders (family Plethodontidae and the clawed salamanders in the family of Asiatic salamanders), no lungs or gills are present, and gas exchange mostly takes place through the skin, known as cutaneous respiration, supplemented by the tissues lining the mouth. To facilitate this, these salamanders have a dense network of ...
These amphibians usually sequester toxins from animals and plants on which they feed, commonly from poisonous insects or poisonous plants. Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, [ 1 ] [ 2 ] and two species of frogs with venom-tipped bone spurs on their skulls, amphibians are not known to actively inject ...
Their habitats are damp woodlands, forests, and places with soft and wet soil. Seasonally flooded areas are essential for breeding, but the adult salamanders are terrestrial. Like many salamanders, marbled salamanders have poison glands to deter predators. [5] The marbled salamander is the state salamander of North Carolina. [6]
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.

Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.
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 ...
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 ...
