1. Owls:
Owls have large, forward-facing eyes that are highly sensitive to light, giving them excellent night vision.
* Large Eyes: Owl's eyes can take up a significant portion of their skulls, providing them with a greater surface area for capturing available light. Larger eyes enable more light to enter the eye, improving their ability to see in dim lighting.
* Retina Structure: The retinas of owls contain a high concentration of specialized photoreceptor cells known as rods. Rods are particularly sensitive to low light levels and aid in detecting movement and shapes in dark environments.
* Tapetum Lucidum: Owls have a reflective layer behind their retinas called the tapetum lucidum. This layer acts like a mirror, reflecting any unabsorbed light back towards the photoreceptors in the retina, increasing the chances of capturing and utilizing dim light.
2. Bats:
Bats also have exceptional night vision, but they use echolocation rather than relying solely on visual cues.
* Echolocation: Most bats emit high-frequency sounds and interpret the echoes bouncing off objects to navigate and locate prey in dark surroundings. This allows them to "see" their surroundings through sound rather than solely visual means.
