* Large, forward-facing eyes: Their eyes are proportionally larger than humans, giving them a wider field of vision. This allows them to see better in low-light conditions, which is crucial for hunting at dawn and dusk.
* Tapetum lucidum: This reflective layer behind the retina acts like a mirror, reflecting light back through the retina and enhancing their ability to see in dim light. This makes them extremely efficient hunters even in moonlight or even starlight.
* Specialized cones and rods: Cougars have a higher density of rod cells in their retinas, which are responsible for detecting light and movement. This helps them spot prey from far away, even when the light is limited.
* Keen depth perception: Because of their forward-facing eyes, cougars have excellent binocular vision, which allows them to accurately judge distances. This is crucial for hunting, as it helps them to accurately stalk and pounce on prey.
Overall, these adaptations contribute to cougars' exceptional eyesight, making them highly successful hunters.
