A salamander is a small amphibian that typically has a slender body, a long tail, and moist skin. They are part of the order Caudata and are found in various habitats, including forests, wetlands, and streams. Salamanders are known for their ability to regenerate lost limbs and tails, which makes them unique among vertebrates. These creatures are primarily nocturnal and feed on insects, worms, and other small invertebrates. Salamanders undergo a life cycle that includes both aquatic and terrestrial stages, often starting as eggs laid in water. They play an important role in their ecosystems by helping to control insect populations.
