Fish are fascinating creatures. They have an amazing ability to adapt to their environment, they’ve been around for a long time and they’re pretty darn cute.

But how much do we really know about them? And what is the truth behind some of the most common myths about fish?

Do fish blink? It’s a question that has run its rounds for millennia. Well, friends, it’s time to get some answers.

What Is Blinking?

In today’s world, blinking is a common occurrence. Most people blink between 10 and 15 times per minute, but that’s not the only thing you should know about blinking.

Blinking is the act of closing your eyes for a short period of time.

Blinking depends on many things, including how often you’re exposed to bright lights (like computer screens), allergies or even by habit.

Blinking is the natural and spontaneous closure of the eyelids to protect the eyes from dust and debris.

Blinking is a reflex action that occurs without requiring any conscious effort.

Blinking is the natural movement of your eyelids, which help you to keep your eyes moist and clean. It also helps to remove dust and other particles from your eyes.

Humans need to blink because it helps moisten the eyes and keeps them healthy.

When we blink, the eyelids spread tears across the eyes, which helps keep them moist. This is especially important for people who have dry eyes.

Blinking is also an immediate reflex to danger—the blinking response causes people to close their eyes when they see a bright light or a potentially harmful object.

When we blink, our eyes are moistened by tears that help protect them from things like dust and debris.

Tears also help keep our eyes lubricated so that they don’t become dry and uncomfortable. This is because human eyes are exposed to air.

While blinking is a reflex, it does require conscious control for some people.

People who have suffered brain trauma may blink less frequently than they did before their injury.

It’s true that fish don’t have eyelids—they don’t need them. Fish are not exposed to air, so they don’t need to moisten their eyes.

They are also not in danger of drying out their eyes, as they don’t blink.

Fish also have faster reflexes than humans, so they can react quickly to danger without needing to blink as a measure of protection.

So yes, fish do not need to blink, and they do not.

Do Fish Close Their Eyes?

You’ve probably heard that fish can’t close their eyes, but is that true?

The answer is yes. Fish cannot close their eyes. They do not have eyelids, so they sleep with their eyes open.

Some species of fish have transparent eyelids, including many types of sharks and rays.

However, many species of fish have no eyelids at all, including herring and salmon.

Most fish sleep with their eyes open because they are unable to completely relax while in motion. This allows them to be more alert for predators and prey during sleep.


The pufferfish is an exception to fish closing eyes. It has a special way of protecting its eyes—its sucks them in!

The pufferfish is an unusual looking creature with a round body and fins that stick out on both sides of its head.

It’s called a pufferfish because it can puff up when threatened or frightened, making itself look larger than it really is.

Pufferfish have no eyelids to protect their eyes, so they have developed another way of protecting their vision: they pull in their eyeballs!

When the pufferfish is frightened and inflates itself into a ball shape, its eyeballs are pushed in where they remain safely tucked away until danger has passed.


In conclusion, fish do not blink. They don’t have eyelids and their eyes are constantly open to help them see better underwater. They have other reflexes to escape from danger and need their eyes to be open to see.

Fish do not blink, but they do have lovely eyes and are great pets to have.
