Some animals have no backbone give me some pros and some cons of having no backbone

Pros:

- Flexibility: Animals without a backbone, such as invertebrates, can often demonstrate greater flexibility in movement due to their lack of rigid support structure.
- Adaptability: Invertebrates can adapt more easily to different environments and terrains due to their flexibility and lack of a fixed structure.
- Regeneration: Some invertebrates have the ability to regenerate lost body parts, which can be advantageous in situations where they may lose a limb or other body part.

Cons:
- Vulnerability: Animals without a backbone may be more vulnerable to predators due to their lack of a protective skeletal structure.
- Limited size: Invertebrates typically have a smaller size compared to vertebrates, which can limit their physical capabilities and abilities.
- Lack of strength: The absence of a backbone can result in reduced physical strength and stamina in some invertebrates, making them less able to withstand certain environmental conditions or challenges.
