snakes dont have eyelids. so how do they sleep?

You just thought so.Snakes have transparent eyelids that is why you may think they do no have eyelids.No sweat.I read it in a book.

Even though their eyes can’t close, snakes have no trouble sleeping. The sleeping response is governed by a portion of the brain, similar to how fishes sleep as well. I have personally come upon snakes coiled on the trail, not aware of my presence for an extended period of time. As many snakes are nocturnal, they wouldn’t neccessarily be asleep at night, but during broad daylight, thanks to their brain controlling the sleep habit.

A snake’s eyes are rounded and with lenses adjustable for distance vision. With the exception of the blind snakes, the eyes of a snake are permanently covered and protected by a transparent lower eyelid (called a spectable or brille). The fusion of the eyelids does not allow a snake to blink or close their eyes. Since the snake lacks external ear openings and eardrums, they hear by using their head to pick up vibrations and sounds from the ground. Experiments have shown that snakes can hear airborne sounds as well, although not well.

a snake’s eyes are always open, protected by immobile, transparent scales.

Snake (reptile), legless animal with a long, flexible body covered with overlapping scales. Snakes are reptiles, a diverse group of animals that also includes lizards, turtles, and crocodiles. Snakes are thought to have evolved from lizards and share many characteristics with this group—particularly the so-called legless lizards, which have tiny, almost imperceptible legs. But unlike most lizards, snakes have thin, forked tongues, and they lack external ears. And while most lizards have movable eyelids that periodically close to protect and lubricate the eyes, a snake’s eyes are always open, protected by immobile, transparent scales.
