Salamanders are tailed amphibians in the order Caudata (also called Urodela). They are mainly found across the Northern Hemisphere with many species depending on moist habitats and freshwater for breeding. A newt is a common-name subset of salamanders often characterized by a more semi‑aquatic lifestyle. Many salamanders are lungless and breathe through the skin and mouth/throat lining, which is why staying moist is critical. Many salamanders can regenerate complex tissues, notably limbs, and in some species the heart and spinal cord.
