How do you classify an invertebrate animal?
The backbone is the observable feature that defines whether the animal is a vertebrate or an invertebrate. These groups are divided into smaller ‘sub-groups’. Sponges, corals, worms, insects, spiders and crabs are all sub-groups of the invertebrate group – they do not have a backbone.

What are two differences between vertebrates and invertebrates?
Vertebrates possess a backbone and an internal skeleton. Vertebrates do not possess an exoskeleton. Nearly all invertebrates possess an open circulatory system.
What are some of the characteristics that vertebrates share?
Vertebrates are differentiated by having a vertebral column. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
