Every living thing sees the world differently. Some animals see the same colors as humans, while others have limited color vision.
One of those animals that sees the world differently is elephants. Their eyesight has helped them survive and navigate the Savannas and forests.
To help you understand why elephants see the way they do, here are six facts about an elephant’s eyesight.
An elephant’s eye is 3.8 cm.
Although elephants are massive in size, their eyes are not that big. African elephants can stand at 8.2 to 13 feet tall and can weigh 5,000 to 14,000 lbs, but each of their eyes is only 3.8 cm (1.5 in).
In comparison to human eyes, an elephant’s eye is slightly larger than humans. A human’s eye is about 2.5 cm (1 in) in diameter.
An elephant’s eyes are located on the side of their head.
You have probably never really taken into consideration where an elephant’s eyes are located. Unlike humans, elephants' eyes are located on the side of their head.
The location of their eyes gives them a better peripheral vision. This kind of vision gives them the ability to see at an angle rather than a central view.
Elephants have poor eyesight.
From what you read stated above, you are probably wondering, do elephants have good vision? The answer is no, elephants have poor eyesight.
Their small eyes and its location limits their vision. These large mammals can only see up to short distances of up to 25 feet away.
Elephants are born blind.
Elephants have the longest pregnancy in the animal kingdom. The average gestation period for these animals is 18 to 22 months. This long period helps to develop the baby elephant (calf) fully.
Although it takes almost two years for an elephant to develop in the womb, it is born blind. Their vision starts to expand throughout the years. African elephant research has found that elephant calves rely heavily on their mothers to survive in the early stages of their lives.
Elephants are colorblind.
Aside from elephants not having good vision, elephants are colorblind. Elephants in the daylight have two kinds of color-sensors: green and red cones.
One of the less known elephant vision facts is that color-blind humans and elephants share the same set of visual pigments. Elephants can see blues and yellows, but cannot distinguish between reds and greens.
Elephants can see in the dark
Elephants spend a lot of time eating and stay up at night munching to get enough food. They run on two hours of sleep each night. Since they spend a lot of time in the dark, they need to be able to see in the darkness.
Researchers have found that elephants exhibit arrhythmic vision - a vision that changes with the time of day. In the night, elephants are more sensitive to blue and violet lights, making it easier for them to see with less light.
