What does metamorphosis mean?

A metamorphosis is a physical change of the animal’s body. It is a transformation from one form to another.

Insects, fish, amphibians, molluscs, crustaceans, cnidarians (jellyfish), echinoderms (sea urchins), and tunicates (sea squirts) undergo metamorphosis.

A complete metamorphosis is called holometaboly.

Incomplete (partial) metamorphosis is called hemimetaboly.

No metamorphosis is called ametaboly.
