Do vertebrates' skeleton grows with the animal and does not have to shed a skin?

Yes, vertebrates have an internal skeleton made of bone or cartilage that grows with the animal as it matures, eliminating the need to shed a skeleton. This growth occurs through the addition of new bone tissue, allowing the skeleton to expand and support the increasing size of the body. In contrast, some invertebrates must molt or shed their exoskeletons to accommodate growth. Thus, vertebrates have a more continuous skeletal development throughout their lives.
