    :crazy:
    A fact from June of 2005 claimed that if a spider does not move its leg(s) for more than an hour that it will stop functioning. Does anyone know any more information about this?

    Yes, I do. As you may know, arachnids have an exoskeletal type structure. This structure provides protection for the spider, and allows it to support weight. The drawback is that the exoskeleton has a tendency to bend during long, prolonged pressure. Any amount of pressure can do this, even the weight of the spider. So, if a spider does not shift it's weight, the exoskeleton around the spider's legs, where it is thinnest, will begin to bend, and pinch off arteries/veins. This obviously disables the spider, and prevents it from doing a whole lot.

    Of course, it is not exactly an hour, and it varies per species and age of the spider, as well as the temperature and humidity. From those studied, members of the Mygalomorphae family required motion more often than members of the Araneomorphae family. But even the least active of the latter family required motion well within an hour.

    Don't worry, the above research is typically funded by pesticide manufacturers, not taxpayer money. I'm more concerned about the publically funded research on spiders who eat insects that feed on poppies.

    Yes, of course, but just for your information, higher humidity/higher temperatures=more required movement.

    In fact, this is theorized to be why spiders originally developed nerve-poison, rather than more typical poisons... for fighting with other spiders. They then developed the "web and externally digest" method of consuming prey that they use today.

    oh yeah is it true that the smaller the spider, the more likely it is to be poisonous??

  8.  

    Ermm...funnelwebs are quite large (around 7 cm) and I think they're the most venomous species of spider.

  9.  

    I always thought it was the Brazilian wandering spider. They are quite large (About 5-7 inches) and kill 5-12 people a year.

    I can pretty much assure you that the most poisonous spiders are native to Australia, like the most poisonous everything else. I'm too lazy to google it right now though.

  11.  

    Yeah. We have many WMDs!:devil:
    By the way, it's 'venomous' for toxins that are injected into the blood or lymph fluid (or whatever it's called). 'Poisonous' is anything else. And poison dart frogs are venomous in a way, because natives take out the poison on their skin and put it on arrows, which are than 'injected' into their prey.
    See? TV can be educational!

    I heard about an Aussie spider that can bite through a mans workboot, what was that one? Brown and small is about all I know of it right now.

    I've always heard that the daddy longlegs spider is the most poisonous, but their jaws aren't big enough to be dangerous to humans.

    Yeah, this seems to be correct, it causes necrosis within a three inch radius around the bite.

    has anyone else noticed that andrés never edits his posts? he seems to slip up quite a bit and never bother correcting it

    Actually it's 1 extra page load to edit a post than to make a brand new post underneath. Furthermore, adding to the database is usually faster than to modify, so Andres is helping out very much.

    I hereby represent Gullible.Info community appreciate Mr. andresoforo. Thank you for your relentless effort in keeping the smooth operation of Fact-check forum.

    It 's an age old question and I'm sure you'd like an answer, well here goes:

    This is a rather difficult question to answer as there are actually a number of very venomous spiders in the world, all of which have caused human deaths (in some cases the reported cases are anecdotal rather than scientifically recorded).

    Of those, the Black Widow Spider (Lactrodectus mactans) of North America is the most well known of the so-called deadly spiders. Other members of the Lactrodectus family are found throughout many temperate parts of the world, such as Australia where it is known as the Red Back spider and New Zealand where it is known as the Katipo spider.

    The Sydney funnel spider (Atrax robustus) of Australia is often quoted as being the spider with the most dangerous venom.

    On the other hand; according to the Guinness Book of Records the world’s most venomous spiders is the Brazilian wandering spider (Phoneutria nigriventer).

    This spider is believed to have the most active neurotoxic venom of any living spider. Its venom is so potent that only 0.006mg (0.00000021oz) is sufficient to kill a mouse.

    http://arachnophiliac.co.uk/burrow/most_venomous_spider.htm

  37.  

    Damn misinformation. The most poisonous spider in the world is those little yellow ones that hide in flowers (approximately 3-5mm long). They spit their venom into the eyes of their prey, which despite the incredibly small volume that actually is administered (apparently they suck at spitting) is enough to incapacitate most small rodents. They have been known to kill and eat everything from grasshoppers to bees to New York Rats (like 6 lbs) when they can get them!!!!
