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.
