Subphylum
From Wikipedia, the free encyclopedia
In scientific classification of biota, a subphylum is a taxonomic rank in zoological nomenclature.
The taxonomic rank of 'subdivision' in fungi and plant taxonomy is equivalent to 'subphylum' in zoological taxonomy.
Taxonomic rank
Subphylum is:
- subordinate to the phylum
- superordinate to the superclass.
Examples
Not all fauna phyla are divided into subphyla.
- Those that are include:
- Arthropoda: divided into subphyla Trilobitomorpha, Chelicerata, Myriapoda, Hexapoda and Crustacea,
- Brachiopoda: divided into subphyla Linguliformea, Craniformea and Rhynchonelliformea,
- Chordata: divided into Tunicata, Cephalochordata, and its largest subphylum Vertebrata.
