Only six amphibians and four land reptiles are native to Scotland. The amphibians include three species of newt: the great crested, of which fewer than 1,000 individuals survive; the smooth, and the palmate. The other amphibians are the common toad, the natterjack toad, found in only four locations in the south-west, and the common frog. A single alien amphibian is known in Scotland, the Alpine newt, a recent escapee confined to the Edinburgh area.

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 their skin is permeable to water, they absorb oxygen and other substances they need through their skin. Scientists study the stability of the amphibian population when studying the water quality of a particular body of water.

Eastern newts eat a variety of prey, such as insects, small mollusks and crustaceans, young amphibians, worms, and frog eggs.
Although eastern newts are widespread throughout North America, they, like many other species of amphibians are increasingly threatened by several factors including, habitat fragmentation, climate change, invasive species, over-exploitation, and emergent infectious diseases. Wild eastern newts are known hosts of "Batrachochytrium dendrobatidis" and "Ranavirus". They are also highly susceptible to the newly emergent chytrid fungus "Batrachochytrium salamandrivorans".

Bulgaria is a country in southeastern Europe situated entirely in the Balkan peninsula. Bulgaria is inhabited by 20 amphibian species, which makes the amphibians the least diverse class of vertebrates in the country. They include seven species of newts and salamanders from a single family, Salamandridae, as well as 13 frog and toad species from five families—Bombinatoridae, Bufonidae, Hylidae, Pelobatidae and Ranidae. The most recently classified species are the northern crested newt, identified in 2005, and the Macedonian crested newt, identified in 2007. Some of the most common species include the European green toad, yellow-bellied toad, and marsh frog.

The smooth newt, also known as the common newt (Lissotriton vulgaris; formerly Triturus vulgaris) is a species of amphibian, the most common newt of the genus "Lissotriton". It is found throughout Europe, except the far north, areas of Southern France and the Iberian Peninsula.

The alpine newt (Ichthyosaura alpestris) is a newt of the salamander order Caudata (or Urodela) in the class of amphibians.
It was formerly known as "Triturus alpestris" and "Mesotriton alpestris".

The amphibian adrenal gland is responsible for the release of corticosteroids and catecholamines which aid in stress response in the newts by maintaining ion and water balance. This allows them to adapt and moderate environmental changes in their habitats. However, the introduction of cadmium into aquatic systems has been shown to disrupt normal operation of the adrenal gland in amphibians and result in a marked drop in ACTH (a hormone secreted by the anterior pituitary gland which triggers an increase in production of corticosterone) and therefore also a drop in corticosterone production. A drop in these necessary hormones severely affects the survivability of the newt, and its hypersensitivity towards chemical and pollutant exposure serves to cripple "T. carnifex"'s longevity further.

The rough-skinned newt ("Taricha granulosa") is a newt known for its strong poison. Habitats of rough-skinned newts are found throughout the West Coast of the United States and British Columbia. Their range extends south to Santa Cruz, California and north to Alaska.

The rough-skinned newt ("Taricha granulosa") is a newt known for its strong poison. Habitats of rough-skinned newts are found throughout the West Coast of the United States and British Columbia. Their range extends south to Santa Cruz, California and north to Alaska. Rough-skinned newts are rare in Idaho and have only been found in several ponds near Moscow, Idaho where they may have been introduced.
