Salamander is the common name applied to approximately 500 amphibianvertebrates with slender bodies, short legs, and long tails (order Caudata or Urodela). The moist skin of the amphibians limits 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.
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 travellers to China were shown garments which, or so they were told, had been woven of wool from the salamander: 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.
The Urodela are Amphibia with elongated bodies and relatively short limbs, devoid of scales or pectoral plates, with numerous præ-caudal vertebræ;, and with amphicœlous, or opisthocœlous, vertebral centra.
The bones of the antebrachium and crus remain distinct, and the tarsus is not elongated.
The Urodela and the Peromela present mere cartilaginous rudiments of a larynx; but, in the Anura, this structure attains a great development, and becomes the instrument of the powerful voice with which many of these animals are provided.
The common name of Salamanders is applied to approximately 350 amphibian vertebrates with slender bodies, short legs, and long tails (order Caudata or Urodela).
The moist skin of the amphibians limits them to habitats either near water or under some protection on moist ground, usually in a forest.
There are ten families belonging to the order Urodela, divided into three suborders:
