Re: do dolphins have eyelids?

Yes. Dolphins do have eyelids. Their eyes also secrete a slippery substance that helps protect them from foreign substances and friction of the water. A dolphin's eyes function independently of one another, meaning that each one doesn't always have to be looking in the same direction as the other, like human eyes do.

Here are two really good websites where you can find out a lot more about dolphins.
