Depending on species, salamanders can breathe through lungs, their permeable skin, or through special membranes in their mouth. Apart from habitat loss and capture for the pet trade, additional threats like harvesting for food, and extensive use in scientific experiments are pushing many species, like the axolotl, on the brink of extinction.

The toxic skin secretion, while not seriously harmful in most cases, can cause vomiting in dogs if ingested. Most species prefer cold, moist environments, living near rivers, lakes, ponds, or around marshes so they can have quick access to water.

However, in our study area, the Kottenforst forest, a deciduous forest in Bonn, Germany, fire salamander larvae can also be found in small ponds and genetic analyses revealed the existence of two genetic clusters corresponding to the larval habitat (Hendrix, Schmidt, Schaub, Krause, & Steinfartz, 2017; Steinfartz, Weitere, & Tautz, 2007).

Salamanders are a group of amphibians typically characterized by a lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. Salamander diversity is highest in the Northern Hemisphere and most species are found in the Holarctic realm, with some species present in the Neotropical realm. Since all amphibians are cold-blooded, terrestrial salamanders do need to hibernate in burrows or under leaf debris during winter to keep themselves from freezing. These carnivorous animals feed on anything they can catch, from insects like beetles, and crickets, spiders, worms, maggots, and flies to snails and other mollusks.

We studied microhabitat use by partitioning containers into microhabitats that either contained or lacked refuges and recorded movement to determine activity. salamander (Salamandra salamandra) in the Kottenforst forest in Bonn, Germany, ex-. Like in all other amphibians, the larval development occurs entirely in water, with the larvae breathing through gills till they complete their metamorphosis, when they lose the gills, and grow legs to move to land.
