<h3>{Differences in Physical Characteristics}</h3>
Vertebrates have a skeletal structure with a spinal column or backbone.Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.
Explanation:
<h3>{Invertebrates}</h3>
•Invertebrates do not possess a backbone not an internal skeleton.
•Invertebrates have an exoskeleton.
•Body size varies but most are generally smaller than vertebrates. However, some invertebrates grow to gigantic proportions – such as the colossal squid (46 feet in length).
<h3>{Vertebrates}</h3>
•Vertebrates possess a backbone and an internal skeleton.
•Vertebrates do not possess an exoskeleton.
•Generally, vertebrates are comparatively larger than invertebrates
