Classification Of Animal Kingdom

All living things on Earth are considered to be part of the animal kingdom, often known as Kingdom Animalia. Animals are multicellular, eukaryotic creatures with sexual reproduction, locomotion, and the ability to ingest organic material. Animals are categorized according to many factors, such as their body composition, rate of growth, and evolutionary connections.
Here is a broad outline of how the animal kingdom is divided up:

1. Porifera (Sponges) Phylum:
Simple, multicellular creatures without genuine tissues or organs are called sponges. They consume nutrition through filter feeding, passing water through their body to filter out nutrients.

2. Cnidaria, Which Includes Jellyfish, Corals, & Sea Anemones:
Radial symmetry and specialized cells called cnidocytes, which contain stinging structures called nematocysts, are characteristics of cnidarians. They have a straightforward body structure, with tentacles around the mouth and a central hollow.

3. Flatworms, Or Phylum Platyhelminthes:
Soft-bodied creatures known as flatworms frequently have flattened dorsoventral surfaces. Their neurological system is straightforward, and their mouth and anus are both contained in the same single hole.

4. Nematoda (Roundworms) Phylum:
Unsegmented worms having cylindrical body are known as roundworms. They can be either free-living or parasitic and are found in a variety of settings.

5. Annelida (Segmented Worms) Phylum:
The segmented worms known as annelids have a distinct body structure made up of recurrent segments. They have a genuine coelom (body cavity) and a closed circulatory system.

6. Phylum Arthropoda:
Arthropods are the biggest phylum of animals and contain an exoskeleton as well as jointed limbs.
They come in a variety of body types, such as insects, crustaceans, arachnids, and others.

7. Phylum Mollusca (Clams, Octopuses,& Snails):
The delicate body of mollusks is frequently shielded by a hard shell. They generally have a visceral mass housing the internal organs and a muscular foot for locomotion.

8. Echinodermata, Which Includes Starfish, Sea Urchins & Sea Cucumbers:
Echinoderms have spiky skin and a distinctive water vascular system that they employ for both eating and propulsion. As adults, they have radial symmetry and frequently have pentamerous body plans.

9. (Fish, Amphibians, Reptiles, Birds, Mammals) Phylum Chordata:
The notochord, dorsal nerve cord, pharyngeal gill slits, and post-anal tail are characteristics of chordates. From fish and amphibians to reptiles, birds, and mammals, this phylum is home to a wide variety of species.

Each phylum in this taxonomy has a large number of classes, orders, families, and species. With more than 1.5 million recognized species and many more still to be found and identified, the animal kingdom is immensely varied.
