A snake’s eyes are very different from our own but they still allow the snake to see the world around them. Here’s a look at how snakes see the world.
The Eye of a Snake
The eye of a snake is very different from our own. For one thing snakes don’t have eyelids. This means that their eyes are constantly exposed to the elements and can dry out easily. To protect their eyes snakes have a thin layer of clear scale called the spectacle.
The eye of a snake is also very different in terms of its construction. The retina is located at the back of the eye and is very thin. This means that snakes have a very small field of vision. In fact snakes can only see things that are directly in front of them.
However what snakes lack in the field of vision they make up for in other ways. For example snakes have excellent night vision. This is because their eyes are very sensitive to light. In fact snakes can see in infrared light which is invisible to us.
The Sense of Smell
In addition to their eyes snakes also use their sense of smell to navigate the world around them. Snakes have a keen sense of smell and can detect even the faintest of odors. This is because they have a special organ called the vomeronasal organ which is located on the roof of their mouth.
The vomeronasal organ is connected to the snake’s brain and allows them to detect chemicals in the air. This is how snakes are able to track their prey.
The Sense of Hearing
Although snakes don’t have ears they are still able to hear. Snakes have a special organ called the Jacobson’s organ which is located on the roof of their mouth. This organ allows snakes to sense vibrations in the air which they use to locate their prey.
The Sense of Touch
In addition to their eyes and ears snakes also use their sense of touch to navigate the world around them. snakes have sensors called pit organs which are located on their lips. These sensors allow snakes to detect heat which they use to locate their prey.
The Benefits and Drawbacks of Infrared Vision
One of the benefits of infrared vision is that it allows snakes to see in the dark. However one of the drawbacks of infrared vision is that it makes it difficult for snakes to see color.
