Caudata is an order of amphibians commonly known as salamanders and newts. They are characterized by their elongated bodies, tails, and moist skin. Caudata species are found in various habitats, including forests, wetlands, and streams, primarily in the Northern Hemisphere. These creatures undergo a life cycle that typically includes both aquatic and terrestrial stages. Most Caudata species lay eggs in water, where the larvae develop before transforming into adults. They play essential roles in their ecosystems, often serving as both predators and prey, and are sensitive indicators of environmental health.
