What is a fish that can blink with both eyes?
No, no fish can blink because they have no eyelids. We blink to regain moisture in our eyes and wash away dirt, but they are surrounded by moisture and water, so there is no need to blink. However, the are a few that have a nictitating membrane (also called the third eyelid) that they "blink". This "third eyelid" is used to protect the eyes.
