No animal is inherently incapable of seeing the sky. All animals with eyes can perceive the sky, though the extent of their vision and what they can see within the sky varies significantly depending on their species.
For example, some animals have excellent night vision and can see stars in the sky, while others have limited vision in low light conditions. Similarly, some animals have a wider field of view than others, allowing them to see more of the sky at once.
Ultimately, the ability to "see the sky" is dependent on the animal's visual capabilities and the specific conditions of their environment.
