Have you seen a bat-eating spider?

According to animal professionals last March of 2013, bat-eating spiders are common and are found all around the world except for Antarctica. 

This spider specie is known as (Argiope savignyi) and (Poecilotheria rufilata), the latter commonly known as the tarantula, were found to trap small bats in their web to eat them.

According to Discovery, they have found 52 instances of this preying from 100 years of reports and observations. This is particular in the North and South of America.

So, would that give Spiderman an edge over Batman?
