Metamorphosis

A dragonfly in its final moult, undergoing metamorphosis, it begins transforming from its nymph form to an adult

Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.[1] Some insects, jellyfish, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior.[2] Animals can be divided into species that undergo complete metamorphosis ("holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis ("ametaboly").[3]

Generally organisms with a larval stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. [4]
