Subphylum

In zoological nomenclature, a subphylum is a taxonomic rank below the rank of phylum.

LifeDomainKingdomPhylumClassOrderFamilyGenusSpecies
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:

  1. subordinate to the phylum
  2. 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:

Examples of infraphyla include the Mycetozoa and the Gnathostomata.

gollark: To be fair, if you look at a support thing like this it'll heavily select for problems.
gollark: It still seems to *work*, but the noise is annoying and I figure relying on it continuing to work with a capacitor blown or something is maybe not smart.
gollark: The nearest repair centres are, according to the website, quite far away, too.
gollark: My device is still warrantied but not having a laptop for ages while it gets repaired would be very inconvenient, so does anyone know how long this sort of thing generally takes to get fixed (or if there is a simple repair I can do, but I doubt it)?
