No they don't , I once watched this animal program and this professor guy said that fish don`'t need any eye lids because they are in water and their eyes all ready get moist. However, sharks are considered a fish and they have eyelids.
I saw a show an Discovery Channel that said they have invisible eyelids like camels and snakes so that their eyes are always protected
no they cannot! they have upper and lower eyelids but they dont move, but they do have a thrid eyelid which is called the nicititating membrane which closes to protect their eyes when biting prey! SO SUCK OUT CHEESTRING YOUR FACTS ARE WRONG! dont belive cheestring facts they lieeeeee
no they dont have eyelids
they have three eyelids i read in a real book about ducks
Fishes have no eyelids as the water in which they live bathes them.insects
Lizards that do not have eyelids include geckos and snakes. Instead of blinking or closing their eyes with eyelids, they have a transparent membrane called a spectacle that helps protect and moisturize their eyes.
Whales and sharks dont have eyelids because instead they metmorphisize

Yes, sharks do sleep, but in a different way than humans. Sharks do not have eyelids, so they cannot close their eyes while sleeping. Instead, some sharks have to keep swimming to keep water flowing over their gills for oxygen. This is called "active rest." Other sharks can rest on the ocean floor or in a cave while still moving water over their gills to breathe.
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.
Fish don't have eye lids, so they never close. But there are exceptional fishes like the Sharks do have eyelids to protect their eyes!
