Subphylum

<h2 id="taxonomic-rank">Taxonomic rank</h2>
<p>Subphylum is:
</p>
<ol><li>subordinate to the <a href="/facts/Phylum/ELT3Jyax">phylum</a></li>
<li>superordinate to the infraphylum, which is in turn superordinate to parvphylum.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a></li></ol>
<p>Where convenient, subphyla in turn can be divided into infraphyla; in turn such an infraphylum also would be superordinate to any classes or superclasses in the <a href="/facts/Hierarchy/mYJyqFrG">hierarchy</a>.
</p>
<h2 id="examples">Examples</h2>
<p>Not all fauna phyla are divided into subphyla. Those that are include:
