Is the Australian Red Back Spider the same as the Amercian Black Widow? The Red Back seems worse.?
448488
Black Widow is considered the most venomous spider in North America.\n\nThe venom of the black widow spider is 15 times as toxic as the venom of the prairie rattlesnake.\n\nA group of spiders that is dangerous in many countries belongs to the genus Latrodectus in the Family Theridiidae. In Australia we have the Redback Spider (Latrodectus hasselti). In America, a common representative of this genus is the Black Widow (Latrodectus mactans).\n\ni would say that they are as dangerous as each other but the black widow killed more than the red back

Female anacondas do not devour the males!\n\n- Praying mantis\n- Many spiders\n- Ceratopogonid midges\n\nhttp://www.yesbutnobutyes.com/archives/ugly_animal_kingdom/index.html\n\n---------\nUpdate: An interesting article that discusses adaptive and nonadaptive hypotheses for sexual cannibalism in spiders.  The evidence suggests that, at least in spiders, there's a connection between foraging decisions and cannibalistic behaviour towards males. \nhttp://www.blackwell-synergy.com/links/doi/10.1046/j.1420-9101.2002.00363.x/full/\n(let me know if you cannot download the article)

Black widows almost never weave a web more than 4 feet from the ground. They don't walk around (the males do but no worries with them) but stay in their nest and wait for bugs to come to them. They like dark quiet places and are not aggressive at all unless you pick em up or sit on them. In fact most bites occur in places with outdoor plumbing. When you sit down in the outhouse, that dark quiet place is just the sort of spot where a black widow lives (all of flies make for lots of spiders!)\n\nA black widow bite is not lethal to an adult (may be for kids). The vast majority of bites lead to nothing but some minor discomfort. The widow's fangs are short - a fraction of an inch and often not as long as your skin is thick - so they aren't able to inject much venom unless they get you in a really tender spot (see outhouse, above).

Deadly is a misleading term, my friend, making it difficult to answer your question.  First there is a distinction between "deadly" and "poisonous" and "venomous".  Deadly spider would entail a study as to how many people have died as a result of an unfortunate run in with the animal or the odds of surviving a bite from the spider.  Then the venom vs. poison debate.  All venom is poisonous, but not all poisons are venom.  If we are discussing spiders and their danger to humans, then we are most likely talking about "venomous" rather than "poisonous".  So a venomous spider would mean one that has the most potent and/or most effective venom.  So here are your answers:\n\nThe Brazilian Wandering Spider is the world's most venomous and deadliest spider.  This is in largly part due to the fact that the spider is very fast, very aggressive, very nervous, does not use "webs" as their hunting tool (note the word "wandering" in it's name), and can and will bite humans.  This spider has the most toxic and deadliest venom known to the world, giving it the title as world's most venomous spider.  It is a South American spider but has sometimes been known to be located in crates of bananas being shipped to the U.S. and other countries, so be careful.\n\nHowever, the Australian funnel-web spiders are among the deadliest spiders in the world in the effect their bites have on humans.  The venom they carry is called atraxotoxin, and is one of the most deadliest toxins known to man.  Only a few of the Australian species are dangerous though, and of the deadly varieteis, the Sydney funnel-web is most encountered.  They are only located in Australia unless kept as pets or for observation elsewhere in the world.\n\nI hope this helped.

matters how scared u r of them if u r terrified and u leave the house if you see one, then u probably need help lol....exposure to them is the best way. first start off small like look @ them on pictures and stuff and then work ur way up to watching movies about them(dicovery chaneel and pbs not 8 legged freaks) and then go lookin for them. watch them there pretty neat. I feed a black widow in my backyard every now and then when im back there its pretty cool how they work. im not helping am i ? lol......

There are probably a lot of spiders that would fit\nyour description. More information is needed, such\nas where (geographically) the spider was seen, in\nwhat kind of habitat and at what time of year.  The\nvarious other answers mostly mention the garden\nor writing spider (Argiope), but it might qualify as\na large spider, depending on what you consider\nlarge.  Another eastern U.S. spider that sometimes\nhas a bright yellow mark and is smaller is another\nof the orb spiders, Verrucosa, which has a triangular abdomen and gets about a half inch long\nin body length.

If you are asking about the Sydney Funnel Web spider, found in Australia, yes, it is a kind of tarantula. Its appearance more closely resembles a trap door spider, with it's hard carapace and shiny black/brown exterior, but the similarities lay in the orientation of its fangs. "True spiders" have fangs that contract from the side on a horizontal axis. A tarantula's fangs thrust downward in a vertical motion, as do the Sydney funnel Web's. The Sydney Funnel Web spider (Atrax Robustus), is only found in Australia, especially distributed in the city of Sydney and areas of close proximity. Like a trap door spider, the Funnel web builds a lair in the ground and lines it with silk, catching prey as it ventures by. This is true of the females, who are larger than the males and spend most of their lives under ground. People often mistakenly dig them up in gardens. The males are more apt to wander, searching for prey and a mate, and are especially active after a rainfall. Both the male and female funnel webs are very aggressive spiders, and the male is more dangerous both in potentcy and because it often wanders into human habitats. The Funnel webs have huge fangs that are capable of piercing a fingernail. When threatened or provoked (not a hard thing to do to a funnel web), it will rear up and expose its fangs, often letting drops of venom form at the tips as a warning. Their venom is a neurotoxin, which affects the nervous system, and depending on the dose of venom, age of victim and their health conditions at the time of bite, the resulting symptoms vary. Death caused by a bite is rare in this day and age, thanks to an anti-venom, developed in 1980. Hope this helps.

I don't feel that any of these women got off easily.  Arachne would probably be my choice for the one who got off the easiest since she was still a living, breathing entity.   Although, I can't imagine being a spider a very nice existence.

I agree completley with you on this one!\n\nYou know I love insects and spiders....well let me tell you whenever I recieve a call about "invaders", the first question is always, What is it? and the second is always How do i kill/get rid of it?\nIts tough for me, because I always try to find peaceful solutions to these problems, but many people dont want to spend that extra 20 minutes spider "proofing" the house, its just easier for them to roll up a news paper....not fair...\nYou raise a good point, their ancestors were here first, then we came along, ruined the habitat and the current wildlife is left with a choice "adapt, or die" and unfortunatly, even though they do adapt to our structures, they usually end up dying anyways because of our lack of compasion. I have never killed a spider in my house, even before i started studying them as a career, I guess because I knew the value of each life and that thye were just trying to do the best with the hand they were dealt (so to speak) so I really dont find it fair that innocent wild animals have to die, just because we dotn want them there, well thank God animals dont think the same way we do, because most likely they dont want us here at all either............. yet Wild animals show much more tolerance than we do....so who is really wild?

More imformation would deffinently help. It is pretty much impossible to tell from the info you gave. What do you mean octagon spider? Does that refer to the web? Some helpful info would be the color, size, and shape of the spider, the shape, size, and location of the web, and where you found the spider (state, country, ect.). Any other information would also help. \n\nAnother thing to consider is that all spiders (other than a small, rare family) have venom. It is unlikely that they are very harmful, but again, I would need more information to say that for sure. Try a field guide (library is a good place to look) and see if you can find what kind it is, then research that one. If you want, post some more info here, and I will try to find it.

Check the windows. they are getting in some where's. They maybe coming in at night and that's why you can't see them during the day. Maybe spiders are night animals....UGH\nI don't know I hate spiders too! Well at least it's a daddy long legs and not a black widow or something....

Hmmm... looks like the common House Spider... but it also almosts looks like the Hobo Spider.... don't worry, these species are harmless but they can be quite a nuisance.

If, on the other hand, you are hoping the spider will survive, I would suggest NOT doing it. Exotic species are a major cause of ecosystem damage and it is often hobbyists or individuals that are responsible for the introductions. I am sure it is also illegal. Governments are very ineffectual in dealing with this problem because it involves trade and lots of money, I hope that individual citizens can be more responsible.

here are some websites if you match the spider up to any of the pictures then just read about it but i dont think it is anything like a black (black with red hourglass shape on back) or a brown recluse because it has a huge white butt and white stripes or dots \nhttp://images.search.yahoo.com/search/images/view?back=http%3A%2F%2Fimages.search.yahoo.com%2Fsearch%2Fimages%3Fp%3Dbrown%2Brecluse%26sp%3D1%26fr2%3Dsp-top%26ei%3DUTF-8%26fr%3DFP-tab-img-t-t400%26ei%3DUTF-8%26SpellState%3Dn-1248453388_q-mmgWoC1th5cTV6Vfxa5u%2FAABAA%40%40&w=300&h=328&imgurl=www.calpoison.com%2Fpublic%2Fbrown-recluse.jpg&rurl=http%3A%2F%2Fwww.calpoison.com%2Fpublic%2Fspiders.html&size=41.3kB&name=brown-recluse.jpg&p=brown+recluse&type=jpeg&no=7&tt=5,138&ei=UTF-8
