General consensus is that the shark (most -- not all types) is the only fish that blinks, however:
Sharks don't blink in the way that we are used to. They have upper and lower eyelids, but these lids don't move and don't close over the eye. When biting prey, some sharks protect their eyes with a third eyelid called the nictitating membrane.
