First something has been divided into phylums - one group. But that wasn't enough, There were still things in that group which needed to be further sorted, so a sub-phylum was created. Let's say you have one group - cars. That's your phylum. Then you have sports cars, that's a sub-phylum.
Sub-phylum is a taxonomic group. A phylum can contain many sub-phylums which contain a huge diversity of species.
