Salamanders are amphibians which are typically cold blooded vertebrates which change from an aquatic, water breathing limbless larva or tadpole to a terrestrial or partially terrestrial air breathing four legged adult that matures and develops lungs. Also included in this group are frogs, toads, newts, and caecilians.
The word amphibian literally means to live a double life, which is exactly what amphibians such as the salamander do. Starting off residing in the water as creatures who have gills and later develop lungs as they age. They are usually required to stay near water to prevent their smooth skin from drying out. Differing from reptiles such as the lizard, these creatures have a soft gel that surrounds the eggs they lay and can usually be found in water or around damp places. Lots of amphibian’s defense against predators includes a type of toxic skin that releases secretions, and many amphibians also bite. These creatures do not have claws or nails as reptiles such as the lizard do.
