Down in Brazil a photographer came upon a strange and somewhat horrific site. It seems a species of spiders native to the area has a habit of spinning community webs high up in the power lines. It makes sense from the perspective of the spider as it can catch more insects to eat with a larger web. Not all spiders are so social and can be downright hostile to other spiders.
In any case, watching the video definitely gave me the chills especially after seeing the LARGER spiders, which appear to be much slightly larger than an adult hand!
