A Brief View on Types and Classification of Metamorphosis

Cassander Martino

Metamorphosis is a natural system by which an animal physically develops after birth or hatching, involving a prominent and generally sudden alter in the animal's body structure through cell growth and differentiation. A few insects, angle, amphibians, molluscs, crustaceans, cnidarians, echinoderms, and tunicates experience transformation, which is often went with by a alter of nourishment source or behaviour. Creatures can be divided into species that experience total transformation ("holometaboly"), incomplete transformation ("hemimetaboly"), or no metamorphosis.
