Division (lat. Phylum) is one of the taxonomic categories in the hierarchical classification of organisms. It stands between class and empire. In botany, the name division is used for this taxonomic rank, while in zoology it is practiced type or circle. Sometimes divisions are divided into subdivisions and microdivisions, or several of them are combined into a superdivision. Analogously, there are subtypes, microtypes and supertypes. Marine organisms are divided into several different phyla. All animals with a backbone, as well as man, together with chordates, are in a special circle, the chordate circle. Other animals are also divided into a large number of types based on some physical characteristics. Some of the more famous ones are: arthropods, arthropods, molluscs, fireflies, echinoderms. The taxon division is between kingdom and class. In some systematics, the animal kingdom is first divided into sections, which are then divided into genera. Bilateral animals are thus partly displayed as a section. In botany and mycology, along with genus (phylum), the term division (divisio) is allowed as a synonym. In bacteriology, the term "genus" is also allowed for clans, more often a group of strains. The kingdom Animalia (animals) includes approximately 35 genera, Plantae (plants) 12, and Fungi (fungi) about 7. More recent phylogenetic studies of relationships in this taxonomic rank place them in larger branches, such as Ecdysozoa and Embryophyta.

General description and known examples

Since Linnaeus' taxonomy, the definitions of zoological genera have changed significantly, especially after the division into six classes and four branches by Georges Kivier. The term phylum was introduced by Ernst Haeckel, based on the Greek word phylon (tribe or branch). In plant taxonomy, Eichler (1883) classified plants into five groups, each called a division. Informally, a genus can be considered a larger group of organisms of lower taxonomic ranks, which are connected by a common, general and/or specialized, plan of body structure. Classifications of organisms in hierarchical systems have been in use since the 17th and 18th centuries. Typically, organisms were grouped according to their morphological similarities, as seen by these early authors, and the groups were then linked according to their similarities to form a hierarchical vertical. At the most basic level, a knee can be defined in two ways: as a group o�
