Salamanders and Newts: General Information

General Description

Salamanders are cold-blooded animals with moist, slimy skins. They usually have four legs and a long tail, although members of the siren family only have two legs. Their bodies can replace lost parts, such as the tail and legs. Most salamanders are less than six inches long, but the Japanese giant salamander (Andrias japonicus) grows up to six feet long. Salamanders cannot hear sounds, nor do they produce any.

Distribution and Habitat

Salamanders and newts are found on all continents except Antarctica, with the greatest diversity being in the United States. They live in ponds, swamps, streams, lakes, rivers, wet mountain forests, and grasslands. One species, the olm (Proteus anguineus), is the only cave-dwelling amphibian.

Reproduction

The female salamander usually lays her eggs in early spring. The eggs are deposited one by one, in groups or in long strings. The larvae hatch from the eggs at different times. In some species, the larva does not leave the egg. The larva breathes through external gills until it changes into an adult. Some kinds of salamanders, called axolotls (Ambystoma mexicanum), keep their larval characteristics throughout life. The female fire salamander (Salamandra salamandra) does not lay eggs at all; it is the only species of amphibian to give birth to live young.

Diet

All salamanders are carnivores. Since they are relatively slow animals, they generally prey on slow-moving, soft-bodied creatures such as earthworms, slugs and snails. Larger species may eat fish, crayfish, and small mammals such as mice and shrews, which are usually taken by chance ambush.

Salamander or Newt?

"Salamander" refers to all Caudates that have tails as adults, including newts and salamanders. The term "newt" is most often used for salamanders that spend most of each year living on land. "Siren" usually refers to salamanders that have lungs as well as gills and never develop beyond the larval stage.
