The animal kingdom is divided into different phyla depending on their characteristics and evolutionary relationships. Some of the major animal phyla include Chordata (animals with a notochord, like vertebrates), Arthropoda (insects, Spiders, and crustaceans), Mollusca (snails, clams, and octopuses), and Echinodermata (starfish and sea urchins).
Phylum Protozoa, Phylum Poifera, Phylum Coelenterata, Phylum Platyhelminthes, Phylum Nematoda, Phylum Annelida, Phylum Arthropoda, Phylum Mollusca, Phylum Echinodermata, and Phylum Chordata are the animal kingdom classifications. It is a long list with many subdivisions.
There is only one animal kingdom. The other kingdoms are plants, fungi, protists, and bacteria. There are also sub-classifications for animals if that's what your looking for. The animal kingdom is split into vertebrates and invertebrates. Of course there are multiple other classifications under those 2 categories.
All animals belong in the animal kingdom. Otherwise, they would not be classified as animals. Animals themselves belong to the kingdom Eukarya, which is comprised of all multicellular life. The other two are Bacteria and Archea.
The animal kingdom is made up of two groups: vertebratesand invertebrates. Some vertebrates are: mammals, reptiles, amphibians, birds, and fishes. Some invertebrates are: molluscs, worms, arthropods, coelenterates, and echinoderms.

The third kingdom was the Kingdom Protista, which was established to include unicellular organisms that did not fit into either the plant or animal kingdoms. Organisms like algae, amoebas, and protozoa were classified under this kingdom.
The second smallest group in the animal kingdom is the genus
The three kingdoms of protists are Protozoa, which are single-celled organisms that are animal-like; Chromista, which includes algae with chlorophyll c; and Plantae, which also includes algae but with chlorophyll a.
Well, if you're talking about animal kingdoms, it'd be eubacteria and archaebacteria. They're both bacteria. I was just learning about this in science class yesterday! :D
