Complete Metamorphosis VS Incomplete Metamorphosis
What is Metamorphosis??
In Biology, animals with metamorphosis undergo abrupt and conspicuous changes of body forms via cell growth and differentiation. Most of the insects, amphibians, and many invertebrates undergo metamorphosis. However, these animals show two types of metamorphosis known as incomplete metamorphosis and complete metamorphosis. It does not mean that one species can show both these two types, but it does mean that certain species undergo incomplete metamorphosis while others undergo complete metamorphosis.

Complete Metamorphosis VS Incomplete Metamorphosis
Incomplete metamorphosis has only THREE stages: Egg, Nymph, and Adult. In each stage of incomplete metamorphosis, the animal looks the same throughout. The nymph looks like a smaller version of the adult. Instead of going into the pupa stage and forming a protective outer layer, the nymph grows into an adult by shedding its outer layers, or its exoskeleton. This will happen many times until the insect/animal is the size of an adult. Once wings develop, the nymph will become an adult and will not longer shed its outer shell/layers. Examples of animals that go through incomplete metamorphosis are crickets, grasshoppers, cockroaches, and praying mantis.
