Dolphins and whales let one half of their brain sleep at a time. This allows them to keep one eye open to watch for danger. They also can still surface to get air, which they couldn't do if they were all the way asleep
The animal which sleeps with one eye open - dolphin
The hare and the rabbit are the animals that sleep with one eye open.
Generally, no. - lies, my dogs twitchin cause he's having some crazy dream about chasing rabbits n what now, YET both his eyes seem to be about 1/3 of the way open, weird eh?
Dolphins, Seals, Birds, Ducks.
Fish & Snake (but they have no eyelids)
Octopus (but they have one eye and can't close it)
It would be extremely rare to see a sheep sleep with it's eyes open. Sheep tend to sleep normally, like other four-legged farm animals.
Yes, they do and and the opened eye won't even flicker at all during sleep.
dolphin
no.
It dosent matter because some people get headaches or an unclear view because they are closing one eye while looking through a small lens. It also can strain your eyes. So you could or you don't have to.
Yes, you can. sneezing is only a reflex action that your body takes to remove an obsticle out from your the windpipe that blocks and/or irritates the flow of air to your lungs. If anything does happen like that, you sneeze and that sneeze can even wake you up. Yes, you can sneeze in your sleep. I'll keep this brief, but since sneezing is a subconscious action, it does not require you to be awake to cause an impulse. yes. Actually no, you can't. IDK why but I found it on the weird facts app on my iPod Touch
no eye-dea
The Cyclopes only had one eye.
Yes. Here's a video showing it... http://video.aol.com/video-detail/daphne-twitching-in-her-sleep-with-eyes-open-pt-1/3708302666 If it's just the third eyelid (the pinkish "haw" that goes from side to side instead of up and down) that is showing, this may be a sign of poor health. When in doubt, ask your vet. Jolo
I believe a shark sleeps with one eye open.
It means you have one eye open. If you mean the idiom "sleep with one eye open," it means that you are staying alert at all times in case of disaster.
they can sleep long with one eye open -they'll drown if both are closed also their eye is open to sense danger or they'll die.
every dolphin sleeps with one eye open.
Sleep with one eye open
At night dolphins will sleep with one eye open close to the surface so that they can breathe when they need oxygen. They leave one eye open so that they can look out for danger while they rest one half of their brain. During the night they will alternate which eye they have open.
Giraffes don't sleep with one eye open. There's no point in keeping an eye open unless there's a brain awake to interpret what the eye is seeing. And the only animals considered to be able to sleep with half the brain at a time are whales and Dolphins.
Dolphins sleep closer to the surface of the water. They always sleep with one eye open and one eye closed and half of their brain working to spot any predators. They keep their blowhole above the water so they can breathe.
this bird sleep with its one eye open
