Final answer:
Vertebrates are animals with a backbone, while invertebrates do not have a backbone.
Step-by-step explanation:
Vertebrates are animals with a backbone, which includes mammals, birds, reptiles, amphibians, and fish. They have an internal skeleton made of bone or cartilage. Invertebrates, on the other hand, do not have a backbone. Examples of invertebrates include insects, spiders, snails, and worms. Cnidarians are a group of invertebrates that includes jellyfish and sea anemones, while echinoderms are a separate group that includes starfish and sea urchins.
