just the great white

Sharks can stop moving and rest in a place with a strong current, they continue to open/close their mouth in the water stream to get the needed Oxygen. Great Whites actually go to the top of the ocean and slowly sink as they rest, then they move back up before they touch the bottom.

Not in the sense that humans do. They have to move continuously to breath. They do, as some studies suggest, rest their brains, as in sleep.

No they don't have to continuously move. I have kept, bred, and raised Guppies, Neon Tetras, Seahorses and (once) a Nurse Shark. They go to a place with a strong current and their mouths face into it. They do not move except for opening and closing their mouths to get Oxygen.

Well, if they are in a current, would that not be simulated movement?

Yeah. When mine do, they float towards the top of the tank but don't flip over. They appear to be stationary. Their eyes are open though because they have no eyelids, therefore making it impossible for them to close their eyes.

Fish sleep but almost in the same way sharks do. They have there eyes open but need to keep moving so its not a deep sleep

Yes, they do sleep.There eyelids are so transparent that one cannot see them with naked eyes.So we can't estimate that a fish doesn't sleep.we can know about it by observing the rate at which it opens its mouth to respire and by its movement of its fins i.e.. there rate of respiration decreases and there fins don't move much.

Most fish do not have eyelids. But there are some, including sharks, that do have a translucent lid that lowers during it's rest period. This allows the fish to sense differences in light and movement while protecting their eyes. What I wonder is...why did evolution leave the rest of the fish species out when it came to protecting their eyes during 'sleep'?

Yes fish sleep, every animal does. They don't necessarily sleep with their eyes open per say - they have no eyelids. Instead of eyelids, they can bring a kind of invisible film over their eyes, they also blink like this.

they turn off one side of there brain at a time, unlike humans we sleep, but they rest one side at a time. but if they become frightened they can immediately turn it back on. like how if someone blows in your eye you blink.

Fish do sleep, in fact. They sleep to regain needed energy just like us, but they don't have eyelids, so they appear to be wide awake when it occurs.

Prefiero was right. Although many aquatic animals such as fish and dolphins, as well as other animals that cannot come to rest on shore, can shut down one half of their brain to rest while the other stays awake to let them escape danger as well as allow air-breathing animals to resurface for air

Sorry, I know you already have a million answers, but I want to tell my story: My pet fish was at the top of the bowl, not moving. I thought he was dead, so i tried to touch him, and he rocketed away so fast that it scared me! So yes, I think fish sleep
