How do nocturnal animals see better in the dark than we can?

Nocturnal animals have evolved specific adaptations that enhance their night vision, allowing them to see better in the dark than humans. They possess a higher number of rod cells in their retinas, which are more sensitive to low light levels. Additionally, many nocturnal species have a reflective layer behind the retina called the tapetum lucidum, which improves light capture by reflecting light that passes through the retina back into the eye. These adaptations collectively enable them to navigate and hunt effectively in low-light environments.
