Answer:
The numerous invertebrates’ phyla are characterized by a wide range of shapes and way of living. All the vertebrates (Vertebrata), instead, have a similar body. Despite their limited differences and the modifications in time, the vertebrates have conquered on just emerged lands, but also the sky. Vertebrates include some of the biggest organisms that have ever lived on Earth and our species also belongs to them
The vertebrates are characterized by a spine, or backbone, consisting of vertebra that surround the nerve cord. Between the vertebra are the cartilage disks, that make the spine a flexible bone structure. Connected to the vertebra are the muscles that allow the movement of the different parts of the spine. These animals have a bone internal skeleton, mainly made up of living material that grows with the animal until it reaches its definitive dimensions.
