metamorphosis

Major alterations in structure and appearance occurring in an organism, such as the human embryo, in the process of its development from egg (ovum) to baby.

metamorphosis

the change in an organism from larval to adult form, which is often quite rapid, as in tadpole to frog, caterpillar to butterfly. Metamorphosis is said to be ‘incomplete’ where there is gradual development of a NYMPH to an adult, as in the EXOPTERYGOTA (Hetero- or Hemi-metabola), e.g. cockroach, locust. It is ‘complete’ where a pupa occurs, as in the ENDOPTERYGOTA (Holometabola), e.g. housefly, butterfly.
