Do spiders have eyelids?


Chris - They don't. Spiders have a compound eyes, so they have lots, and lots of individual lenses that then filter down through this lens material, onto a photo receptor, a light-sensitive plate underneath so they don't have a call for having any kind of eyelid type structure. Their eyes are open all the time, so they'll keep an eye on you because they've got plenty of them.
