some people on this board should really refrain from making threads.

I dont know what LeRoy is talking about, but I'm referring to some threads that seem to only be created for the purpose of just being the OP
at what age do parents mainly mothers stop referring to their offspring as "my child"

Why do animals sleep?
Why do animals sleep?
Speaking of sleeping animals...
...How do fish (whales, sharks, etc.) sleep? They're supposed to stay in constant motion in order to breathe. How the hell do they manage to get rest and stay alive?
I think your biology may be a little twisted. Fish dont have to remain in constant motion to breathe. Most fish find places in their habitat to "rest" or sleep if you will by remaining motionless for some period of time. It is usually done at night near under water rocks or coral or other such things that can protect them from night time predators.
to conserve energy...
why does almost everyone think that bear hibernate
You might be right. I thought I did hear things about sharks needing to stay in motion. I could be wrong though...
You could make the evolutionary argument that it's counter-productive for animals to go into a state of unconsciousness, where they're more vulnerable to predators.
So why sleep?
Prove It...^^^^^ for some reason, this discussion is starting to turn me on
It makes intuitive sense that it would be to conserve energy, replenish metabolism, "reboot" neurological functioning etc.
But why sleep?
I mean, there are studies that wounds tend to heal faster during sleep. But control experiments show the same rate of healing during conscious rest or dormancy.

So why sleep?
I think you're right, sharks do. I can't remember why exactly but i think it has to do with their gill structure and how they breathe.

I am really loving this nice cold rainy day of hibernation! Spring cleaning begins after my nap
Right, it has to do with their need to keep water flowing over/through their gills so they can breathe...Damnit, when does Shark Week begin? The Discovery Channel is what we need right now.
www.elasmo-research.org/education/topics/b_sleep.htmSleep is one of the last bastions of mystery that Science has yet to conquer. Despite several centuries of study, speculation, and debate, we still really don't know what sleep is or why we need to 'shut down' periodically. We know that all sorts of vertebrate animals – mammals, birds, reptiles, and at least some fishes – periodically enter a period of torpor characterized by a profound change in brain waves.
But when it comes to whether or not sharks sleep, we just don't know. There have been reports from all over the globe, including Mexico, Japan, and Australia, of sharks resting motionless in caves. These have been called "sleeping sharks", but I can attest that the eyes of these quiescent sharks do follow divers moving about in the caves with them, so they're definitely not asleep.
In his sweeping epic Paradise Lost, 17th Century English poet, John Milton, asked, "What hath night to do with sleep?" We know from sonic telemetry studies (the underwater equivalent of radio tracking) that at least some shark species — such as the Reef Whitetip (Triaenodon obesus) and the Tiger Shark (Galeocerdo cuvier) — are actually more active at night than during the day. Since schooling behavior is partially coordinated by vision, many other sharks are most active at dawn and dusk, when such prey is at a disadvantage. Studies such as these suggest that at least some sharks do not sleep at night.
We used to think that the Great White Shark (Carcharodon carcharias) was primarily active during the day. But it turns out that this is largely due to observer bias: humans tend to be diurnal rather than nocturnal, and it's very difficult to watch an underwater creature at night. Recent experiments by Peter Klimley using stationary telemetry pods placed along the bottom at the Farallon Islands, we have learned that White Sharks are quite active at night, when they probably feed primarily on bottom fishes. If these bottom fishes are sleeping when attacked, they're certainly in for a 'rude awakening'!
Because sharks rely on ram-ventilation — that is, their forward swimming to push oxygen-bearing water through their mouths and over their gills — this fact begs the question: do sharks sleep at all? Dolphins are conscious breathers, actually having to think about rising to the surface, opening their blowholes, and breathing. From Russian studies carried out in the early 1970's, we know that dolphins catnap in 2 to 3-minute stretches, actually shutting down one hemisphere of their brain at a time. From experiments carried out on a small shark called the Spiny Dogfish (Squalus acanthias), we know that the 'Central Pattern Generator' that co-ordinates swimming movements in sharks is not located in the brain, but in the spinal chord. Thus, it is possible for an unconscious shark to swim.
There is even a possibility that the sharks' fore, mid-, and hind- brain shut down in sequence, resulting in the shark equivalent of sleep-walking.
What? Our conversation about animals (e.g. those in the oceans and seas)? If so, why is that?
I think it's the exchange of information between men that has nothing to do with sports or sex; I'm a bit of nerd so I love learning new things...
I was thinking the same thing...
*rubs hands together and laughs evilly...*
Show me yours and I'll show you mine
If it wasnt for Denise the show show would have too perfect....I miss those days when all of the bills in the mailbox were addressed to my parents...
I like seeing black couples out and about, especially with children..
I wonder why I like that show, Candy Girls so much.
The Cosby show is the shit
If it wasnt for Denise the show show would have too perfect....
I disagree, Vanessa actually caused them alot of problems, even though she was supposed to be the really smart one. Most of my favorite episodes are about Vanessa.
drink er down... that was a great episode "mom dad you can't make rudy drink" "shut up and drink" drink er down
yep and the episode where she snuck off to Baltimore. "You were off to see the wretched to have big fun" "but mom.." "don't answer me when I'm talking to you" -classic

Most animals are never in a state of full unconsciousness. You may think an animal is sleeping but notice it's ears, and eyes, they are usually barely open.
wouldn't a full unconscious state mean that said animal is dead or brain dead if you will
I see fully unconscious people walking around all the time.
