Salamander

Salamanders are a group of amphibians typically characterized by a lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All present-day salamander families are grouped together under the scientific name Urodela. Salamander diversity is most abundant in the Northern Hemisphere and most species are found in the Holarctic ecozone, with some species present in the Neotropical zone.

Diet of the Wild Salamander
The salamander enjoys a variety of bugs and critters in the wild. What he eats is dependent on his size. He will eat almost anything that moves and is small enough that he can swallow it. The wild salamander dines on centipedes, worms, spiders, slugs, maggots, flies, termites and snails. Large salamanders include frogs and smaller salamanders in their diets. Aquatic salamanders in the wild consume insect larvae, worms, crayfish, snails, tiny fish and other small aquatic animals.

Life Cycle
The tadpoles have external gills in wing-like forms attached to either side of their heads, just where they should have their necks. With time, as the tadpoles grow and metamorphose into Salamanders, their external wing-like structure shreds off.
