Ostriches Eyes Are Bigger Than Their Brains


Have you ever heard the saying, ‘Don’t believe everything you see’? Well, that definitely applies to ostriches. These towering birds may look like they have it all together with their long legs and fluffy feathers, but there’s one surprising fact about them that will blow your mind: their eyes are actually bigger than their brains. Yes, you read that right! In this blog post, we’ll dive into the science behind this bizarre phenomenon and explore what it means for these fascinating creatures. So buckle up and get ready to learn something new about one of nature’s most peculiar animals.

Introduction to Ostriches and Their Anatomy

Ostriches are the largest living bird in the world. They are native to Africa and can grow up to 9 feet tall and weigh more than 350 pounds. The ostrich is easily recognizable by its long neck and legs, and its distinctive two-toed footprints.

The ostrich has a small head with big eyes that are set far back on its head. This design helps the ostrich see predators from all directions. The ostrich also has long eyelashes that protect its eyes from sand and dust.

The ostrich’s brain is only about the size of a walnut, which is much smaller than its eyes. Scientists believe that this is because the ostrich’s eyes need less blood flow than its brain.

The ostrich’s heart is also very large, weighing about 1 pound. Ostriches have a high metabolism and need to eat frequently to maintain their energy levels.

Ostriches are herbivores and eat mostly plants and vegetables. They will also eat insects, lizards, and small mammals if they can catch them.

The Surprising Fact About Ostrich Eyes

Ostriches have the largest eyes of any land animal, and they are also proportionally the biggest. Each eyeball is about the size of a billiard ball, and their eyes are so big that they take up about as much space in their skulls as a human brain does. So how does an ostrich see with such big eyes?

The answer lies in the fact that ostriches have very good binocular vision. This means that they can see clearly in front of them, but their peripheral vision isn’t as sharp. So while they may not be able to spot a predator sneaking up on them from the side, they can definitely spot one coming straight for them!

How the Myth of Bigger Eyes Began

A long time ago, people used to believe that ostriches stuck their heads in the sand to avoid being seen. This belief likely started because of a misunderstanding of how these birds actually behave. When an ostrich feels threatened, it will lay low to the ground and keep its head close to the ground as well. From a distance, it may look like the ostrich has buried its head in the sand.

This mistaken belief might have also been fueled by the fact that ostriches have relatively small brains compared to their body size. In fact, their brain makes up just 1-2% of their total body weight! So, when people saw Ostriches with what appeared to be small brains, they assumed that they must be stupid birds that didn’t know any better than to bury their heads in the sand.

Of course, we now know that ostriches are far from stupid! These incredible birds can actually run up to 40 miles per hour and they can also fly short distances. They are also excellent at camouflage and can blend in perfectly with their surroundings.

So, next time you see an ostrich, remember that these fascinating creatures are much more complex than they appear!

The Truth Behind the Myth: Why Ostrich Eyes Appear Bigger than their Brains

It’s a common misconception that ostriches have eyes that are bigger than their brains. In fact, the opposite is true! The ostrich’s brain is actually very large relative to its body size, and its eyes are proportionately smaller.

So why do ostriches appear to have such big eyes? It’s all an illusion created by the placement of their eyes on the sides of their head. This gives them a much wider field of vision than we have, which is why they’re so difficult to sneak up on!

While their eyes might not be as big as we thought, they’re still pretty impressive. Ostriches have the largest eyes of any land animal, and they can weigh up to 3 ounces (85 grams). That’s about the same as a human eye!

How This Affects Other Parts of an Ostrich’s Body

The size of an ostrich’s eyes is directly proportional to the size of its brain. As a result, ostriches have the largest eyes of any land vertebrate in proportion to their body size. Because their eyes are so large, they take up a significant amount of space in the skull. This leaves little room for the ostrich’s brain, which is only about the size of a walnut.


From the anatomy of their eyes to their surprisingly small brains, ostriches have a unique set of features that make them one of the most fascinating creatures on this planet. While it’s true that their eyes are larger than their brains they still manage to survive and even thrive in many different climates around the world. The next time you see an ostrich take a moment to appreciate all its amazing features and remember that things aren’t always what they seem!
