They sleep...right after Mrs. Paul gets hold of their butt! Her and that Gorton Fisherman guy...oh and Long John Silver.

Not as we would define it. They go into a semi-conscious state, but remain responsive to danger / sudden disturbance, so it is not true sleep. They dont need it as their brains are not complex enough to demand it.

Correct. The reason people think they never sleep is because they have no eyelids, so they can't close their eyes.

The memory span of a fish, contrary to popular belief, is not less than 3 seconds, but several days. Just wanted to throw that in.

Everything sleeps. Sharks have to keep moving in order to force water through their gills in order to breathe, but they can do it in a sleep state.

I remember when I was a young kid out partying till 3 in the morning and I had to be to work at 6:00 am. I actually found myself falling asleep as I was walking sown the aisle with my journeyman. Yup, my eyes were closed and I was asleep but my body kept walking.

So there are, as everyone knows, different levels of sleep. In the REM sleep the mind disconnects the voluntary muscles from the brain so that you aren't moving your limbs during sleep. That's why so many people complain that they have a nightmare where something terrible was happening but when they tried to run away they couldn't move (or run fast enough).

EDIT: Now you need to ask, "Do fish dream?" 🙂

Yea I've partially lost consciousness when walking to work too, its a bizzarre feeling, your definitely still walking and semi-aware, but at the same time your definitely asleep..... Its very disconcerting.....

I Couldn't agree more. I've also had this feeling when coming home from a party and listening something calm on my earphones, like Bob Marley - No Woman, No Cry.

I was once so tired that I fell asleep while making love. 😞
You know I had to be exhausted to do something like that!

The girl under me said, "HEY! ARE YOU FALLING ASLEEP ON ME!?" 😲

And that was w/o missing a stroke, so I think that goes to prove that the body can continue to function even when the mind goes into an unconscious state.

Yeah, I hate to think of those days. *sigh*

I'm sure Dr Callum Brown will have some work published on this subject.
