Salamander
Salamander (/sæləˈmændər/) is a common name for approximately 500 species of amphibians. They are 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.
Etymology
The term "salamander" is derived from the Greek word "salamandra" which originally might have referred to a mythical creature believed to be able to live in and extinguish fire.
Anatomy
Salamanders have a typical amphibian anatomy with features that distinguish them from other members of their class. They have a moist, smooth skin which is associated with a number of glands that produce secretions to keep the skin moist, enabling them to respire through their skin.
Habitat
Salamanders are found in most parts of the world but are most numerous in the Northern Hemisphere. They are most abundant in areas with a temperate climate.
Diet
Salamanders are carnivorous, feeding on a variety of organisms including insects, spiders, worms, slugs, and other small animals.
Reproduction
Most species of salamanders undergo a process of metamorphosis which involves a change from a juvenile water-breathing form to an adult air-breathing form.
