Subphylum
In zoological nomenclature, a subphylum is a taxonomic rank below the rank of phylum.
The hierarchy of biological classification's eight major taxonomic ranks. Intermediate minor rankings are not shown.
The taxonomic rank of "subdivision" in fungi and plant taxonomy is equivalent to "subphylum" in zoological taxonomy. Some plant taxonomists have also used the rank of subphylum, for instance monocotyledons as a subphylum of phylum Angiospermae.[1]
Taxonomic rank
Subphylum is:
- subordinate to the phylum
- superordinate to the infraphylum.
Where convenient, subphyla in turn may be divided into infraphyla; in turn such an infraphylum also would be superordinate to any classes or superclasses in the hierarchy.
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.
Examples of infraphyla include the Mycetozoa and the Gnathostomata.

gollark: <@!282594912682115074> Have you tried:- waiting- Incubate- Kill- ARing- more hatcheries?
gollark: Wait, where are you getting the flipmints from? The AP?
gollark: > sees "2g saltkin; want any 4 hatchlings" on hub> frantically clicks> notices lack of 4 hatchlings
gollark: Turpentines aren't *that* rare, are they?
