Even though sharks are among very few fish which have eyelids, they do not blink. Most species of sharks have special nictitating membranes which go over their eyes to protect them when they are hunting or under attack.

Is a wink the same as a blink?
There is a difference, a blink is to close and immediately reopen the eyes, usually involuntarily, as when the eyes are affected by strong light. A wink is given, usually with one eye, with the eye closed a little longer that a blink, giving a hint or a signal which may have some sly meaning. Often the head is inclined at the same time at add greater effect. ^^That's true. Blinking is usually with both eyes, and usually in comes naturally. (We have to blink at some point, and it's usually an subconscious act). A wink is only with one eye and is usually meant to signalize something.
