You mean like 50ft spiders eating humans in the prehistoric era?
When have spiders ever been a large threat to humans?
A few years ago I was watching Today Tonight and this family had hundreds of funnel webs in thier backyard.
The whackiest thing about it is that funnel webs are not common at all in Victoria. They are rare down here.
Spiders are not the type of species that would go out of their way to hurt/kill a human. A funnel web is more likely to run away from you then bite you, unless you are provoking it until it hits boiling point which in case it would try to strike you. Then again if you provoke anyone until they reach boiling point they will kick your ass.
I have always wandered, if you pick a spider by it's back and it's fangs can't hurt you, will the back of the spider secrete poison to hurt you? Or is it safe to pick up a spider by it's back assuming it's fangs can't touch you?
