To put it into context and to share in my own skin crawling realization on just how big that is I want you to remember the Alien movies. Remember those nasty face-huggers that would crawl around and leap out at it’s unsuspecting victim, wrapping it’s self around their face.
The size of this spider is around the size of the face-huggers from the Alien movies. That is huge
It’s a nocturnal hunter using trap doors to get it’s prey.
