Pufferfish are renowned for the fantastic ability to puff themselves like a balloon when feeling threatened. Did you know that it's also the only species of fish known to blink? It is rather interesting that this could be quite impossible, yet it remains the truth! Puffers are unique and possess a unique manner of safeguarding their eyes, distinguishing them from other fish species.

Why Do Fish Normally Not Blink?

Most fish don’t blink. Instead of eyelids, they have a clear, protective covering over their eyes called a "nictitating membrane." This keeps their eyes safe from dirt or damage. But puffers are different—they actually have eyelids! These eyelids let them blink, just like humans and other animals.

How Blinking Helps Puffers

Puffers dwell in water that is often muddy and laden with debris. They don't have eyelids to rub off dirt or small pieces that may enter their eyes. However, the blinking feature prevents the puffers from any irritation of their eyes through such particles. Just as we blink to clean out our eyes and feel good about them.

Feature for Protection

The eyelids of puffers are not merely used to clean the eyes. They protect the very sensitive eyes also. Living in areas with low visibility, the ability of having eyelids that blink allows them an additional method for staying healthy and safe.

Unlike other fish, which just have a thin protective covering over their eyes, puffers can actually close their eyes with eyelids. That's one of the reasons they are so unique as one of the most peculiar fish in the sea.

Inflating for Defense

Besides blinking, puffers also inflate when they feel threatened. It makes them look much bigger than they are, which is scary for predators. They can fill their stomachs with air or water in a few seconds and blow up like a balloon.

Both of these capabilities; blinking and inflating help the puffers survive in their natural habitat. By blinking to clean their eyes, and by inflating to scare the predators, they have become clever enough to protect themselves.
