Salamander is a common name of
approximately 550 extant species of amphibians. They are typically characterized by a
superficially lizard-like appearance, with slender bodies, short noses, and
long tails. All known fossil salamanders and all extinct species fall under the
order Caudata, while
sometimes the extant species are grouped together as the Urodela. Most salamanders have four toes on
their front legs and five on their rear legs. Their moist skin usually makes
them reliant on habitats in or near water, or under some protection (e.g.,
moist ground), often in a wetland. Some salamander species
are fully aquatic throughout life, some take to the water intermittently, and
some are entirely terrestrial as adults. Unique amongvertebrates, they are capable of regenerating lost limbs, as well as other
body parts. Many of the members of the family Salamandridae are known asnewts.
