There is no animal that cannot see in the day. All animals have some level of vision, even those that are primarily active at night. However, some animals, like owls, bats, and cats, have adapted to see better in low-light conditions. This doesn't mean they are blind during the day, just that their vision is optimized for nighttime.
Here are some examples:
- Owls: Owls have large eyes and pupils that can dilate widely to allow more light in. Their retinas also have a high concentration of rod cells, which are more sensitive to light than cone cells.
- Bats: While bats rely primarily on echolocation, they still have eyes and can see in the dark. Their vision is not as sharp as that of other animals, but it allows them to navigate and detect movement.
- Cats: Cats have a special reflective layer behind their retinas called the tapetum lucidum that reflects light back through the retina, increasing their light sensitivity. This is why their eyes appear to glow in the dark.
While some animals may have difficulty seeing in bright sunlight, they are not completely blind during the day. They simply have different visual adaptations that allow them to thrive in different lighting conditions.
