Why classification of animals is important

For example, they differentiated animals on the basis of: food they consume, respiratory system and utility for humans. Authors suggest that more stress should be put on these aspects during designing lessons about animal classification.

Example: Annelids, Arthropods, Chordates. Radial Symmetry: When the body of an animal can be divided into two equal halves along any plane passing through the central axis is known as radial symmetry.

Example: Cnidarians, Ctenophores, Echinoderms. Figure Showing Metamerism or Segmentation. Figure Showing Body Plane and Axis. Figure Showing Germ Layers. Aurelia aurita Cnidarians. Beroe cucumis Ctenophorans. Figure Showing Coelom Types. The body cavity is filled by mesenchyme and muscles. They are found in phylum Platyhelminthes, Nemartea.. These animals are found in phylum Nematoda, Acanthocephala, Rotifera, Entroprocta. Starfish Echinoderms. Ampullaria globosa Molluscs.

Taenia Platyhelmints. Ascaris Nemathelminths. Non-chordates: These are animals without a notochord. Example: Phylum Porifera to Echinodermata. Chordates: These are animals with the presence of notochord. Example: Phylum Chordata. Principles of Animal Classification. Kingdom 2. Phylum 3. Class 4. Order 5.

Family 6. Genus 7. Species and Sub Species. Nomenclature of Animal. Rules of Binomial nomenclature. Each animal should have only one scientific name; the same name should not be used for two or more species under the same genus. Each binomial name should have two parts.

The first part refers to the name of the genus and the second part to the name of the species. Both the name should be printed in letters or else they should be underline separately. For example, Felis leo or Felis leo. The name of the genus is noun which should start with a capital letter and the name of the species is adjective and start with a small letter. Name of the scientist who first identified and described the species should be abbreviated and written after the species name, preferably in brackets.

For example, Homo sapiens Linnaeus is written as Homo sapiens L. According to the law of priority that scientific name of an animal should be acknowledged which first published in an international journal. The generic and specific name of an animal may be of the same. For example, Catla catla. This provision is called tautonym. The specimen used as a sample during identification and naming should be preserved as a type specimen in the laboratory.

If the proposed name is identical in spelling to another such name, that belongs to a different taxon. This is called a homonym. If the proposed animals have an earliest valid scientific name, this name is known as a synonym. Both homonym and synonym have their senior and junior entity. The earliest such name is called the senior while the later name is the junior. According to the law of priority only senior homonym or synonym approved as a valid name for an animal. Importance of Animal Classification.

A classification system is a useful tool which helps to identify the animal taxa on the basis of the interrelationship among different groups of animals. It helps to know the animal kingdom. In this case, by studying classified animals anyone can gather knowledge about animal kingdom with minimum time and less labor.

The classification systems provide relatively stable, unique and unequivocal names for newly identified animals. The classification system is also a very useful tool for understanding the phylogenic relationships between different groups of animals. Classification system provides information to identify beneficiary animal species and thus help in the selection of economically important animals. Download citation.
