The animal kingdom is divided in phyla, for example the phylum Arthropoda. Each phylum is subdivided in classes, for example the class Hexapoda (= insects). Classes are subdivided into orders, for example the order Coleoptera (= beetles). Orders are divided into families, families into genera (singular: genus), and genera are divided into species.
