1. Increased flexibility: A backbone allows for greater range of movement and flexibility compared to an exoskeleton, which is rigid and limits movement to the joints of the exoskeleton.
2. Lightweight: A backbone is typically lighter in weight compared to an exoskeleton, which can be bulky and heavy, restricting movement and causing discomfort.
3. Energy efficiency: A backbone allows for more efficient movement as the muscles are directly attached to the bones, allowing for smoother and more precise movements, while an exoskeleton may require additional energy to operate and move.
4. Adaptability: A backbone can grow and adapt as the organism grows and develops, whereas an exoskeleton must be shed and replaced in order for the organism to grow.
5. Protection: A backbone provides internal protection for vital organs, while an exoskeleton provides external protection from predators and environmental hazards.
6. Sensory capabilities: A backbone allows for better integration of sensory information from the environment, as the nerves are directly connected to the spine, while an exoskeleton may limit sensory input due to being an external structure.
