why do spiders legs crumple into their bodies when you squish them?

no, its not a pain response.  spiders are different from us in that they don't move by contracting long muscles as we do.  we move around by the contraction and relaxation of long muscle groups in our bodies.  a spider on the other hand, uses its blood as a hydraulic fluid.  it moves by pumping the blood in and out of the legs, extending and contracting them in the process.  so, when you 'squish' a spider you remove all the blood---and the legs contract as a result of not having any blood pumped into them to extend them.\n\nPS===don't squish spiders.  they are beneficial to us.

Spiders are so ugly because they are arachnids! They have 8 legs and are meant to creep you out! But they are the only reason in which this planet is not been taken over by all them dumb bugs and instects!

They're called "Little Red Spiders That Live On Walls".\n\nMites, actually.

Many different types of tree-leaf feeding caterpillars do this; there are at least two reasons. As forex says - if a predator, like a spider, approaches, some species drop on a line of silk to avoid getting eaten. At other times and with other types of caterpillars, they dangle on a line because they're ready to turn into moths. They need a safer place to make a cocoon and pupate so they dangle until it feels right and then, hopefully, the wind will blow them into a lower, warmer and safer place to spend the winter in their cocoon. In the spring, they turn into moths and lay eggs on the leaves of the same type of tree that they grew up on. They’re usually small moths that nobody ever sees - unless they look. They spin silk from modified salivary glands which secrete a strong, elastic thread through spinnerets right next to their mouths; it’s similar to spider silk but their own recipe.

My mom and sister like to put hedgeapples in their attics and basements. I guess the spiders steer clear, esp. of those rooms. The spiders won't completely leave, but the number of spiders is supposed to decrease.

Spiders can bite and sometimes do for no reason.  They also are usually nocturnal (coming out at night).  \n\nMost spiders can not bite through human skin.  The ones that can are fairly rare and are usually known locally and eradicated.  (At least in the US)\n\nBefore you fear something, its a good idea to look to those with more experience (time).  I've lived with spiders for more than 4 decades and have only been bit once, and it wasn't much worse than a mosquito bite.  So ask those around you to lay your fears to rest.

The skin on your palms, fingers, soles of your feet, and toes is thicker, so when it absorbs water, the surface of them buckles.  You will find that other parts of your body will wrinkle up as well, usually around the hands and feet.

They're called sweat pimples. Nothing to worry about. They form when you sweat alot on your legs, normally starting about now and ending when the weather cools. Just pop them like zits, but don't squeeze them to death. They'll stay red and swollen and look like they'll need popping for a few days after but they won't, just let them heal. In the mean time, do wear shorts and let your legs breathe. That's probably most of your problem.\n\nNote: You probably don't have lyme disease, chiggers, and I doubt you're getting bit by spiders. This is a normal thing that every male I know gets, including myself.

They know which strands are the sticky ones and which aren't.  I think it's impossible for a spider to stick in its own web.\n\nhttp://arachnophiliac.co.uk/burrow/whydoesnt.htm

like it's already been stated, with spiders the female tends to be larger, also in some cases the female will eat the male when the fertilization is complete.\n\nBut as for a special chamber inside the female to store the male...never heard of that

IF you have streaks that are darker/lighter running up your ankle, that is a sure sign of bacterial infection. Bug/spider bites can give a serious infection. Sounds as if you may have brown recluse spiders in your home. Get to a doctor immediately...this is nothing to play around with. Make sure before you put your shoes on that you shake them out very well...bang them on the floor, etc.  Some spiders, including recluse and black widows, love shoes to build webs in.

Spiders dont really sleep in the sense that they close there eyes in dream but depending on the spider they do have time periods where there metabolic rate slows down. Usually if its like a spider that uses its vision to hunt it will slow down at night, where as a spider that uses its web and senses to hunt it will slow down in the day.

because they have strong muscles in their legs and they are top heavy        ?

Yes, please see a doctor at once. This could be related to a bacteria, which is a flesh-eating bacteria. Goes through the circulatory system, often shows up in the legs / ankles area.

Yes. Many spiders build their webs so that they are more than two feet from the ground.

The incorrect answer is C. Spiders will NOT accept dead insects. They only eat the fresh ones (otherwise we'd have a lot less dead insects around).\n\nHope this has helped you!
