Lemurs have big eyes primarily because they are nocturnal animals, meaning they are most active during the night. These large eyes help them to see better in low light conditions. The eyes of lemurs are adapted to enhance their night vision, allowing them to navigate their environment and find food more effectively when it’s dark.
The size of their eyes is associated with a larger pupil, which can take in more light. Additionally, lemurs have a high number of rod cells in their retinas, which are specialized for low-light vision. This adaptation is crucial for their survival, as it enables them to avoid predators and find food in the shadows of their forest habitat.
In essence, the big eyes of lemurs are a specific adaptation that suits their lifestyle and helps them thrive in a nocturnal environment.
