what salamanders are most closely related and how do you know?
Salamanders are typically characterized by their slender bodies, short noses, four limbs or limbless and long tails.They belong to class amphibia (can live both on land and in water). They are closely related to frog and toads
Their moist skin usually makes them reliant on habitats in or near water, or wetland. Some salamander species are fully aquatic throughout life, some take to the water intermittently, and some are entirely terrestrial as adults.
Like other amphibians they are coldblooded, show metamorphosis from water breathing juvenile form to terrrestrial air-breathing adult or may retain juvenile characteristics like in most salamanders.They show cutaneous respiration or respiration through skin, also use gills and sometimes lungs to respire.Lay eggs in water.
