Salamander (orig. from Persian: sām, Fire, and andarūn, Within) is the common name applied to approximately 500 species of amphibians with slender bodies, short legs, and long tails. The moist skin of the amphibians fits them to habitats either near water or under some protection on moist ground, usually in a swamp. Some species are aquatic throughout life, some take to the water intermittently, and some are entirely terrestrial as adults. Salamanders superficially resemble lizards, but are easily distinguished by their lack of scales. They are capable of regenerating lost limbs. The earliest known salamander date back 161 million years (prior to the extinction of the dinosaurs), and were very similar to modern members of the Cryptobranchoidea.

The name derives from an old belief that salamanders could walk through fire, which is false.

[edit] Habitat

Species of salamanders are numerous and found in most moist or arid habitats in the northern hemisphere. Most are small but some reach up to 5 inches (12.7 cm) in length. They live in brooks and ponds and other moist locations such as under rocks. North America has the hellbender and the mudpuppy which can reach the length of a foot (30 cm) or more. In Japan and China the giant salamander is found, which reaches 6 feet and weighs up to 30 kilograms.[1][2]

Salamander habitat is generally restricted to mostly the northern hemisphere, with the exception of a few species living in the northernmost part of South America. Although common on the European mainland, salamanders are not a native species of either Great Britain or Ireland.
