See radial and bilateral symmetry below. Encyclopedia of Life. Taxonomy Phylogeny. Natural Perspective: Animal Kingdom. The Animal Kingdom is at once the Kingdom most and least familiar to us.
Almost all of the animals we commonly think of -- mammals, fish, and birds -- belong to a single subgroup within one of the 33 Phyla comprising the Animal Kingdom. On the other hand, over 100,000 species in some 25 animal phyla -- mostly small worms -- are so unfamiliar that they are virtually unknown to non-scientists. The same goes for several hundred thousand tiny insect-like species populating the Arthropoda phylum.
