Some of the differences are, that Invertebrates tend to be small and slow moving. Vertebrates, on the other hand, are stronger, faster and most times, bigger.
Also Vertebrates have more highly developed nervous systems, giving them the chance to understand better, and faster than Invertebrates. Invertebrates have an exoskeleton on the outside of their body, but Vertebrates just have a skeleton on the inside of their body. And most importantly, Invertebrates have no back bone but vertebrates do.
so basically the biggest difference is tthat vertebrates have backbones and invertebrates don't

invertebrates have no spine, vertebrates do
