Metamorphosis

Metamorphosis is a biological process in which an animal undergoes a conspicuous and relatively abrupt change in its body structure as part of its development. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, often accompanied by a change of nutrition or behavior. Some animal species undergo complete metamorphosis ("holometaboly") between radically different lifecycle stages; others have incomplete metamorphosis ("hemimetaboly") between somewhat similar stages, or no metamorphosis ("ametaboly").

Organisms with larval stages undergo metamorphosis to the adult stage.
