Most organisms must have a period of sleep but ive never heard of a t sleeping, or any other invert.
Do tarantulas sleep?

Fruitflies sleep
. There's a lot of studies on the effect of sleep deprivation in flies. So, if flies can do it I'm sure T's can too.

Their metabolisms work incredibly slowly, a book I read went as far as calling them the 'walking dead'. I think every single one of us can attest to the fact that they're usually inactive. So, I wouldn't say they have what we'd call "sleep".
Ts cannot fly and therefore don't need to rest from flight. I'd imagine that this would cause a bit of variation in metabolic rates.

but all of them can run and sum really fast
I would assume all living organisms have some form of sleep. It might not be the same form of rest that we experience, but I believe they have something similar. It does not matter if they rest much of the time or have low metobolic rates. Even if you sat in a chair every day all day and had almost no physical activity, you would still require sleep.

That is simply anthropomorphizing them. Their physiology is completely alien to ours; you can't make any kind of comparison where a human is doing something.
...In short bursts. Certain Ts can move really fast, but they run out of steam inversely proportional to it. You might loose sight of that spider, but it's still nearby.but all of them can run and sum really fast

Even the animals that lack brains? I don't know what your family members have told you, but "all animals" is a broad statement and nature doesn't pigeonhole so easily.
Wait, now I'm straying from my own point. What I am trying to say is that this state of "reduced brain function" is a tarantula's default mode where it's more than capable of springing back into action at any point.

Yeah lol I was going to say! As far as I'm aware, all multicellular animals have some kind of nervous system and at least a very basic nerve centre which would count as a simple brain

Porifera lack nervous systems altogether. Others have only nerve clusters such as Cnidaria, Ctenophora and Echinodermata.
You can call a vague bunch of nerves a "brain" if you want to be unscientific, but you can't argue about Porifera.

I know several, but I wont name names
I agree. I think a T has what we would call "sleep", however they do not take much time at all to become alert, unlike most humans.
Haha, now that I think about it, I agree...I know several, but I wont name names

I had a Grammostola Rosea that slept 23 hours a day!!!
Interesting...I hadn't thought of that.

They don't sleep... they wait.
Thanks for the info, very intersting.
Going back to the topic at hand though, tarantulas definitely do have a simple kind of brain. In light of this I would argue that if simpler invertebrates have been found to sleep then more complex organisms like tarantulas probably do it too, and the reason we are having this debate is that they don't show any external sign of sleeping. For example, they don't curl up on top of their hide, close their eyes and visibly drift off like a cat would.
Completely BTW, I have a pair of geckos of a species that don't close their eyes, so they don't seem to show any signs of sleep either. Sleeping with your eyes open, I really wonder what that would be like

that would be a bit far fetched as well. i dont know if u guys have ever really experienced this, but even some of the more quick to bolt or not so friendly T's that ive encountered can be "Startled" if u catch them at the right moment, u move them with a pencil or pair of tongs and nothing happens, give them a slight nudge and they more or less sit there, do it again and its an explosion of panic...running every which way until they gain some sort of idea whats going on and then they react. perhaps its not sleep but i know im certain ive even caught my OBT off guard...got right on top of her, and even moved her around a bit and then BANG she came off like a bat outta hell but it wasnt her normal reaction, it was more like a "WTF is going on....im going to bite things" so...i would have to go with there IS a rest period for them, but at what level we can compare it to sleep im uncertain...i dont have the scientific background to know that.

I think this may be the most correct answer IMO. Here is a link show a bit of the TKG http://books.google.com/books?id=qN...&resnum=1&ved=0CBIQ6AEwAA#v=onepage&q&f=false
I think the deal is that on some level they rest but it might not be the same as human sleep. if you read after the part about sleep it gos on to talk a little about some cycles that they go through and I found that really interesting too.
