Shark’s most interesting secret
We bet you didn’t know they had any!
- Sharks, like other fish, do not blink the way humans do. While they still do blink, they do it differently.
- This is because of the presence of nictitating membranes, which act as protective eyelids over their eyes. However, not all sharks have nictitating membranes.
- Sharks employ these membranes to protect their eyes from any injury while hunting.
- So, when they do blink, they do it, using both of their eyes.
- There is a special membrane that protects their eyes when they are feeding or hunting. So, when fighting their prey, this membrane protecting their eyes, gives the impression that they are blinking.
- Sharks blink occasionally using their third eyelid, known as the nictitating membrane, to close their eyes.
- As a result, even though this is a brief process, sharks remain in a closed eye state when hunting or resting.
