Salamander is the common name applied to approximately 500 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 forest. 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.

[edit] Physiology
Their ability to switch between swimming and walking makes them interesting animals to study the evolution of animal locomotion during vertebrate evolution. The two types of gaits have been studied using neuromechanical simulations <ref>Salamander locomotion.</ref>.
Adult salamanders who retain their external gills are called perennibranchiate species.
Some salamanders retain their juvenile, gilled morphology but become sexually mature in a process called neoteny. The axolotl, Ambystoma mexicanum, is a textbook example of a neotenic salamander, although there are many more neotenic species within the Ambystoma species complex. The juvenile form is retained to avoid the rigors of terrestrial life.
[edit] Reproduction
The female members of the suborder Salamandroidea have cloacal glands in their cloacal chamber called spermathecae used to store sperm, as well as cloacal lips to pick up the male spermatophores.
The suborders Cryptobranchoidea and Sirenoidea have external fertilization.
[edit] Habitat
Species of salamanders are numerous and found in most moist or aqueous habitats in the northern hemisphere. Most are small but some reach up to 5 feet (1.5 m) in length. They live in brooks and ponds and other moist locations. 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 5 feet (1.5 m) and weighs up to 30 kilograms <ref>Digitally tagging and releasing.</ref><ref>International Giant Salamander Protection Site.</ref>.
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.
[edit] Mythology
The mythical salamander resembles the real salamander somewhat in appearance, but makes its home in fires, the hotter the better. (Similarly, the salamander in heraldry is shown in flames, but is otherwise depicted as a generic lizard.) Early travelers to China were shown garments supposedly woven from salamander wool; the cloth was completely unharmed by fire. The garments had actually been woven from asbestos. Later Paracelsus suggested that the salamander was the elemental of fire. Because of this, salamanders have often been associated with dragons because of their connection with fire. These myths originate in Europe from the fire salamander, Salamandra salamandra, which hibernates in and under rotting logs. When logs were brought indoors and put on the fire, the animals mysteriously appeared from the flames.
King Francois I of France used a salamander as his personal emblem.
