2. Pit Organs: Some snakes, especially vipers, pythons, and boas, possess specialized pit organs that detect infrared radiation, allowing them to “see” the body heat of prey, which is invaluable for hunting in darkness.
3. Spectacle: Snakes don’t have eyelids. Instead, they have a transparent scale, called a spectacle, protecting their eyes.
4. UV Vision: Some snake species can detect ultraviolet light, enhancing their ability to locate prey or mates.
5. Parietal Eye: Certain snakes have a light-sensitive “third eye” on top of their head, which aids in regulating circadian rhythms.

These mechanisms collectively enhance a snake’s visual prowess, ensuring they can effectively hunt, navigate, and communicate in their respective habitats.

The Distinctive Retinas and Cones of Snakes

The retinas of snakes are specialized structures that play a crucial role in their vision. Here’s a closer look at their retinas and cones:

1. Retinal Composition: A snake’s retina contains both rod and cone cells. Rods are responsible for low-light or nocturnal vision, while cones manage color and daylight vision.
2. Cone Diversity: Snakes have a varying number of cone types. Some species possess multiple cone types, allowing them to discern a range of colors, while others might be more limited.
