When we think of spiders, we tend to think of them weaving complex webs in advantageous places and waiting patiently for their prey to stumble into their trap. It’s this lack of active aggression that makes arachnids just a little bit less terrifying.

But not all spiders are so passive. Many have advanced hunting skills and abilities that allow them to go on the offensive, and it’s pretty scary.

That’s some impressive tracking ability. But how exactly can a spider do that? And more importantly, should we be afraid?
