The most common classification scheme for all animals is the Linnaean system, which categorizes organisms into hierarchical groups based on shared characteristics. This system includes categories such as kingdom, phylum, class, order, family, genus, and species.
Phylum is the second broadest classification grouping for animals, following Kingdom. Phylum divides animals into major groups based on general characteristics such as body structure and organization. Examples of phyla include Chordata (which includes vertebrates) and Arthropoda (which includes insects and crustaceans).
