- ‘I'm animal, my phylum is chordata, my subphylum is vertebrate, my class is mammals, sublass theria, infraclass eutheria, within that I'm a primate, and within that I'm human.’
- ‘To give the idea of a subphylum, the entire Vertebrata are in the Linnean arrangement a subphylum of the phylum Chordata.’
- ‘Technically an invertebrate, amphioxus is classified in subphylum Protochordata, phylum Chordata.’
- ‘These aren't just distinct species but distinct phyla, categories so large that man and bat occupy not only the same phylum but the same subphylum.’
