There is no single animal that cannot see at night. All animals have some level of vision, even if it's limited in low light conditions.
Some animals, like owls and cats, have excellent night vision due to adaptations like:
- Larger pupils: Allowing more light to enter the eye.
- Highly reflective tapetum lucidum: A layer behind the retina that reflects light back through the retina, increasing light sensitivity.
- More rod cells: Photoreceptor cells that are more sensitive to low light.
However, even animals with limited night vision can still see in some darkness. For example, while humans don't see as well at night as owls, we can still navigate and perceive objects in low light.
Therefore, the question "Which animal cannot see at night?" is not accurate. All animals have some level of vision, even if it's limited in low light conditions.
