I stepped on a small spider..looked like a miniature daddy long legs..when I stepped on it to kill it..it bled a lot. Just wondering why that would have happened.

Actually spiders have colorless blood, yes they bleed but it won't be red colored like animals and humans do. http://www.xs4all.nl/~ednieuw/Spiders/InfoNed/blood.html

Spiders don't have the same circulatory system as humans, and don't really have blood. Instead of like veins and stuff they more or less have this one big cavity that has this fluid that gets sloshed around the whole body. Sometimes in insects they have a heart which pushes this fluid from one part of the body to another, and if it is big enough, it will have minor tubes leading from the big hollow central one into other parts of the body, kinda like veins, but really just like tubes. there really isn't a circulatory system, just a big bag of goo that gets pushed around. They don't have blood either, not like red blood like us. This goo can be any color, and is usually black or green or something like that.
