Watch the full video of Metamorphosis in Animals: Definition, Types & Examples

Immaku.com this time we will discuss Metamorphosis in Animals – In a process in biological development in animals where the appearance or structure changes after birth or hatching.

There are two types of metamorphosis in animals, namely complete metamorphosis and incomplete metamorphosis. Supposedly perfect, because the shape of the larva is very different in the shape of the picture.

In this discussion, we will explain about Metamorphosis in Animals. For a full review, come on… Check out the following explanation.

What is Metamorphosis In Animals?

Metamorphosis In Animals

Metamorphosis In Animals is a process in biological development in animals in which the appearance or in a structure can change after birth or hatching.

The physical changes that can occur due to a cell growth and cell differentiation are radically different. Some insects, molluscs, echinoderms, amphibians, crustaceans, and tunicates go through a process of metamorphosis that is usually (but not always) associated with a change in behavior or habitat.

Kinds of Metamorphosis

Metamorphosis is a process in animal development and growth that occurs with significant physical changes (physiology, morphology and anatomy) from egg to hatch and changes to become an adult animal.

During the growth process, animals experience various changes to the cycle. There are several types of insects and amphibians that have different body shapes at a young age and eventually grow up.

In addition, in the form of a metamorphosis cycle, which can be used as a basis for grouping the types of insect animals. Insect metamorphosis can be divided into two types, namely imperfect metamorphosis and perfect metamorphosis.

1. Complete Metamorphosis

Complete metamorphosis or holometabolism is a process in the type of growth in an insect that corresponds to a change in form at a young age until the animal finally grows up.

In holometabolism, the animal form changes from a larva to a pupa (adult animal). With complete metamorphosis, animals pass through four stages, namely egg, larva, cocoon and imago (adult animal).

  • counts, In this phase the result of fertilization between sperm and egg, namely the embryo, can undergo a division of cells until the main organs are formed.
  • Larva, It is at this stage that a physical change has occurred in some types of animal exoskeleton, in which molting occurs. Over time, the animal’s body grows, causing the skin to change.
  • Pupa, In this stage there is a transition in a total in which a new form is formed. At this point, the animals will reduce in their eating habits. But the doll grew until adulthood passed into an adult stage.
  • Imigo, In this phase it has a new animal forms which were formed differently when the animal was young. And animals reproduce to form a new egg, which then passes through the egg, larval, and pupal stages and becomes an imigo.

Examples of Complete Metamorphosis Animals

Some examples of animals that carry out a complete metamorphosis are butterflies, flies, mosquitoes, bees, wasps, frogs, and so on.

2. Imperfect Metamorphosis

Imperfect metamorphosis or hemimetabolism is a process in the development and growth of animals with certain organs that experience changes in physiological types. The incomplete metamorphosis phase, namely egg, nymph, and imago (adult animal), here is the explanation:

  • Egg Phase, At this stage, the mother can store an egg in a safe place to protect the embryo from attacks by other animals. The egg is then covered with a layer of chitin, which has a protective function for the embryo until the egg hatches into a fairy.
  • Nimfa phase, In the nymph phase, it can start by forming an organ that is almost similar to an organ in an adult animal.
  • Phase Image, In this stage, various changes have occurred in the animal until the animal is mature and ready for reproduction.

Examples of Incomplete Metamorphosis Animals

Incomplete metamorphosis occurs in 3 stages, namely egg, nymph and imigo. Some types of animals that can carry out a process in an imperfect metamorphosis are grasshoppers, cockroaches, and so on.
