While spiders have muscles to flex their spindly limbs inward, they use hydraulic pressure to extend them outward. Almost all other limbed animals have both flexor and extensor muscles, which produce smoother, less jarring, and much less unsettling movements. To extend their legs, spiders rapidly increase pressure in their cephalothorax -- the round, bulb-like midsection to which all the legs are connected. This increase in pressure sends hemolymph (blood) flowing to the extremities, causing the legs to stretch outward. When moving, spiders innately increase and decrease body pressure in fractions of a second to quickly skitter about. http://www.realclearscience.com/blog/201...

Awesome! I like spiders (except when they're on me).
My school does! Was a fantastic class and I highly recommend it to anyone who has the opportunity to take it! Learned so much
Cool! They have one?
I only know because I just got done taking an Arachnology class ;)
Shoot! I heard incorrectly then. Sorry!
Not true, Joshua. There is an entire family of spiders that don't even have venom glands, family Uloboridae.
All spiders are venomous, but only some are dangerous to humans.

Thanks Dante! That means it could be venomous?
Loxosceles, but i'm not sure for the form of the palps.
