Well crap.
Actually, those are a different arachnid called Daddy-longlegs. They don't have fangs nor are they venomous. But still, no one wants them anywhere close.
Spiders have two-segmented bodies and are usually solitary, not clumped together in a colony like that. Harvestmen also don't have fangs or venom. Still, I wouldn't want a bunch of them thrown on me. ;)
