Welcome everyone – today we’re here to talk about the eye of snakes. This incredible organ has some fascinating features which we’ll look at in a bit more detail. So without further ado, let’s jump right in!
Fact 1: Snakes have better vision than humans in some ways. Snakes have a superior ability to detect certain wavelengths of light, allowing them to create a more detailed picture of their surroundings. While they can’t detect colour, they can sense ultraviolet and infrared light – something that even our own eyes can’t do.
Fact 2: Snake eyes are protected by a specialised structure. To protect their eyes from dust, dirt and other irritants, snakes have a seal-like cover which blocks out these particles and reduces glare. As an added feature, some species of snake also have transparent eyelids – allowing them to see even when their eyes are closed.
Fact 3: Snake eyes can rotate independently from one another. This feature allows them to see in multiple directions at once, which is especially useful for finding prey. When targeting prey, their independent eye movement allows them to judge distance and focus on the intended target.
Fact 4: Snakes can sense slight changes in light levels. Thanks to a special form of photosensitivity known as ‘pit organs’, snakes can detect slight changes in light levels, even when they’re in total darkness. These are located on the sides of their faces, near the eyes and enable them to detect when an animal is nearby.
Fact 5: Snakes have specialised lenses designed to help them focus. Snake lenses are smooth and curved, allowing them to focus on distant objects without having to adjust the shape of their eye. As a result, they can quickly and accurately detect prey or predators that may be further away.
Fact 6: Snakes have pupils that change size to adapt to different situations. Depending on environmental conditions, snakes can adjust the size of their pupils – allowing them to increase or decrease the amount of light that enters the eye.
Fact 7: Most snakes have binocular vision. This means they can use both eyes at the same time in order to better judge distance and size – an invaluable tool when hunting prey.
Fact 8: Some snakes have an extra eye feature known as a ‘pinhole pupil’. While it’s not as effective as binocular vision, it’s useful for measuring the size of objects that are too small for their regular eyesight.
Fact 9: Snakes are colourblind. Contrary to popular belief, snakes are unable to see colours – although they may be able to detect shades of grey and yellow due to their heightened sensitivity to UV and yellow light.
Finally, Fact 10: Snake eyes contain ‘spectral filters’ which help them hunt in the dark. These filters can block out all light except for particular wavelengths – allowing snakes to locate their prey even if it’s dark outside.
So there you have it – 10 incredible facts about the eye of snakes! Thanks for watching – we hope you learned something new today!
