Salamanders live in water and on land, and look rather like lizards, with four legs and a tail. They hatch as larvae from eggs in the water. At that stage, they have gills that stick out. Most salamanders live on land when they are adults, after their change of shape (metamorphosis). On land, salamanders live in moist habitats. Their method of respiration varies. Some salamanders stay in the water, but look like adults.
