Adaptation

 

The Lesser Bush Baby has very large eyes, which help it see in the nighttime. In the daytime, its iris is able to contract to form a small, vertical ellipse. During the night, the irises become completely circular. The retina is also covered in cone cells, which helps with light absorption. By becoming larger during the night and containing many cone cells, the eyes of the Bush Baby absorb more light and have excellent night vision. Since these animals are nocturnal, night vision is critical for their survival in order to see predators and look for food.
