| Now a team of paleontologists has found a fossilized arthropod they're betting is an early member of the subphylum Crustacea. |
| Technically an invertebrate, amphioxus is classified in subphylum Protochordata, phylum Chordata. |
| Going on down the hierarchy are phylum, subphylum, class, subclass, order, family, genus, species. |
| To give the idea of a subphylum, the entire Vertebrata are in the Linnean arrangement a subphylum of the phylum Chordata. |
| 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. |
| In other schemes the phylum Arthropoda is retained and the major taxa are given subphylum or class status. |
