The indented list below shows some of the major taxonomic categories used in classification. Many other categories exist between those shown. In large groups with a well-resolved phylogeny the number of categories can approximate the number of species. Clearly the use of higher taxonomic categories can get out of hand. At present there is little agreement on how to handle this problem.
