The human eye is a pretty amazing thing, but let’s not forget about our animal friends and their peepers.

We’ve put together a list of some of the most amazing facts about animals and their eyes, from extra eyelids to eyes the size of footballs.



Owls

facts about eyes

Known for their nocturnal lifestyles, owls boast eyes adapted to darker conditions. Their corneas and pupils are larger than most other birds, while their retinas feature plenty of rod cells that make them extra sensitive to light.

While its often thought that due to having superior vision at night owls can’t see very well during the day, they actually have pupils that offer a wide range of adjustment, meaning they can determine the amount of light that hits the retina.

You’ll also know of their ability to rotate their heads a full 270 degrees without any problems, which helps them see their surroundings even better. And lastly, we promised you extra eyelids, and owls deliver on that with a whopping three eyelids, including one that closes diagonally!

Chameleons

facts about eyes

One of the most curious animals around, the chameleon is a sight to behold with its ability to change colour. These little reptiles also possess pretty exceptional sight themselves. Their eyelids cover almost the entire eye, with the exception of a small hole that lets the pupil see through. This means that they’re still able to see even when their eyes are “closed”.

In addition to this, their eyes are able to move independently of one another, making it easier for them to track multiple targets at feeding time.

Camels

facts about eyes

Camels are best-known for their distinctive humps that allow them to survive the adverse conditions of the desert. But they possess a number of other features that help them to navigate through the harsh sands.

First, there’s their long eyelashes which work like dusters and are attached to two sets of eyelids. Both of these features work to shield their eyes from sand. A final, and thinner, set of eyelids helps to wipe their eyes clean. Camels can also slightly see through these last eyelids, which is a massive advantage during sandstorms or days with higher winds.

Goats

facts about eyes

Seen by many as just another farmyard animal, goats actually possess some of the most amazing eyes in the animal kingdom.

Unusually, their pupils are rectangular, which allows them a 320 field of vision and means that they don’t have a frontal blind spot.

The Giant Squid

facts about eyes

We’ve saved the most amazing animal on the list for last. The giant squid boasts the impressive status as the animal with the largest eyes on the planet! Each eye is around 25cm (10 inches) across, roughly the same size as a football.

To put their massive eyes in perspective, even the blue whale (the largest animal in the world) only has eyes of around 11cm across.

The theory behind the giant squid’s giant eyes is that they have developed as protection from sperm whales. These whales often disturb creatures that emit light as they swim through the ocean, tipping off the giant squid who can see light from up to 120m away.



We hope you learned a thing or two from our list of facts about these five amazing animals! Let us know which fact surprised you the most and if you have any facts of your own that you’d like to share with us.
