there is no difference because they are the same thing. ( look at you spelling)
there invertabrates
Invertabrates are not divided; if they were, they'd die.
Both are arthropods
Well what makes them invertabrates is that they don't have back bones or spine.
Chordata is a phylum, vertabrate (vertabrata) is a sub-phylum. Although this is not well-known, the phylum chordata contains some (very few) invertabrates (animals without a backbone) such as sea squirts. So the phylum chordata is futher classified into 2 sub-phyla, vertabrata (vertabrates) and invertabrata (invertabrates).
