Can Spiders walk backwards?

Don't know, but at night they take out mini pieces of kitchen lino and have breakdancing competitions with food and web upgrades for prizes.

Yes, some cockroaches run on their rear legs only for increased speed- If you can get hold of a YA member named "Jag", she can answer you more fully-she's an entymologist.

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

It is an interesting question related to surfaces and dimensions. The easiest answer appears to be  1 ft + 30 ft + 11 ft  i.e.  42 ft. This is the distance if the spider choses to traverse across the three walls.  But if the spider takes a different route crawling across the side wall, I believe the distance can be shorter.

I'm pretty sure on a web only some of the web is sticky. The spider just knows where to put its feet. I think... Or maybe its just the opposite of how a fly lands unside down on the ceiling.

About 75 percent scuttle sideways, the better to keep an eye on approaching predators.\n\nAlso, Because that's the way their legs bend. Muscles work in pairs. A muscle can only retract, or pull; to lengthen again it must relax and be pulled back by another 'antagonistic' muscle.

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.

actually, insects have 6 legs, arachnids (spiders) have 8.\n\n6 legs is actually a very efficient and simple mode of moving.  When an insect walks the front and rear legs on one side along with the middle leg on the other move in lock step while the other 3 form a stable platform for the insect.

not according to this site: http://dermatology.cdlib.org/DOJvol5num2/special/recluse.html\n\nif you scroll down, it shows both the range, and some pics. also, if you're asking because you have a nasty, nectrotizing wound, it gives at least one example of a Pacific Northwest spider that can do that.

Crabs run or move sideways because that is the way their legs bend. Crabs do not have ball-and-socket joints; many crabs have joints in their legs moving in a restricted number of planes so that they can only move sideways. Many crabs like the "Shore Crab" need to scamper sideways to avoid the legs getting tangled up with each other. \n\nMuscles work in pairs. A muscle can only retract, or pull; to lengthen again it must relax and be pulled back by another 'antagonistic' muscle. The muscle blocks in crabs are attached to the inner surface of the exoskeleton, including the ten tubular legs, including the legs with claws, or chelae, as well as other appendages.\nAslo,For animals, their body lengths are normally larger than the widths. For locomotion, animals usually move along the long axis of their bodies. As crabs run sideways, they are moving along the long axis of their bodies.

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.

Spider do not senses like insects, so insect repellent is no good. You just have to see and avoid. What you can do is to carry a stick in front of you so that you get rid of any potential webs that may be across your path. And spider along the way. This is good against spider on web on trees. Ground spider will be harder to see and avoid. Wear boots or high cut shoes.\nBut you should relax, they are more scared of you than you of them! You are so much larger in size! Anyway most spiders are harmless to humans except for a couple, so don't get too worried about them.

Arachnophobia - fear of spiders.

I doubt it is a Brown recluse. They kill other spiders. They kill eachother. Thats why they are reclusive.\n\n Just get a man to spray your house. You'll be ok.\n\nBacon & Salt?  hmmmmm. I have used  Potato peels.\n\nThey work good.\n\n\n.

Yes..as weird it may sound. Their trunk acts like a 5th leg.\n \nJust like a spider monkey, where the tail acts as fifth arm.
