Amphibians originated from from a tetrapod. Early tetrapods were like fish but may have had limbs to move on the bottom of marshes. In later fossils, the limbs were found further below to lift the animal off the ground. Eventually, amphibians arose the ability to breath through the air as well as water.
No. Fish breathe through gills and have scaly skin. They have fins and no true limbs. Amphibians breathe throgh gills during development stage then convert tro lungs. Most then grow limbs and have naked (no scales) skin. Examples of amphibians are frogs, newts, salamanders and toads.
Amphibians started out as tetrapods, fish like creatures that used limbs to move across the bottom of a marsh. In later fossils the limbs moved under the body so it could support itself. Later, it gained lungs so it could live outside of the water.
