I won't keep you in suspense anymore. I present to you....
The Spiny Orb-Weaver Spider!Creepy, right?? That crab-looking thing is part of the spider! Read about it on Wikipedia using this link. Check out this wiki-link, too, it's more specific to the species I found.
This spider will not die tomorrow but it will have to find a new home. I only want the little kiddos to find plastic spiders when they come for candy next week!
(AmyB, I know this creeps you out, but I had to make you a little freaked out at least one more time before you leave!)
