Young amphibians are a group of animals that includes frogs, salamanders, and newts. They are characterized by their ability to live both in water and on land. The term 'EFTS' is an acronym for 'Egg-Frog-Tadpole-Salamander, ' which is a common life cycle of many amphibians. This life cycle begins with eggs laid in water, which then hatch into tadpoles. The tadpoles eventually develop into frogs, and then the frogs become adults and lay eggs of their own. Salamanders also go through a similar life cycle, but they do not have a tadpole stage.
