Phylum

Rare card · No. 41403

In biology, a phylum (, FYE-luum; pl.: phyla) is a level of classification, or taxonomic rank, that is below kingdom and above class. Traditionally, the term division has been used in botany instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent. Depending on definitions, the animal kingdom Animalia contains about 32 phyla, the plant kingdom Plantae contains about 14 phyla, and the fungus kingdom Fungi contains about eight phyla. Current research in phylogenetics is uncovering the relationships among phyla within larger clades like Ecdysozoa and Embryophyta.
