Solution

DIFFERENCES:

1) Vertebrates have a backbone or spinal column, have an internal skeleton made of bone, an advanced nervous system with a developed brain and have outer covering of protective cellular skin.
Invertebrates have no backbone, no cell walls. They are heterotrophic.
Because of developed brains, vertebrates have better and faster understanding than invertebrates.
2) Examples of vertebrates are humans, primates (gorillas, monkeys, orang-utans), marsupials (kangaroo, koala), reptiles (crocodiles, lizards, snakes), birds, seals, dolphins, mammals. Examples of invertebrates are insects, flatworms, jellyfish, flies.
3) Vertebrates are stronger, faster and mostly bigger than the invertebrates. Invertebrates tend to be small and slow moving.
4) 2% of animal species are vertebrates. Rest 98% are invertebrates.
5) There are 57,739 species of vertebrates. In comparison, there are 2 million species of invertebrates that have been identified . More remain to be identified.
6) Vertebrates have only bilateral symmetry. Invertebrates have bilateral or radial symmetry.
7) Vertebrates are classified into 5 groups; invertebrates into 30 phyla.
