Gina and I are even. I saved her once, and she saved me.
The spider back there was extremely poisonous. Gina calls it the blowfish spider.
If you step on it barefoot, it can kill you. It has poisonous sacks all around it's body.
If it bites you, nice knowing you.
They generally don't like people, but they love birds. Birds tend to see the spider's chubby back as a landing spot and that's when the poison is absorbed into the body, through their feet. It takes about 2 minutes. It's more than enough time for the bird to relax, groom itself for a bit and become powerless food.
Gina watched a woman step on one and I guess it's pretty painless. You just start to feel more and more numb until you can't move. Sad thing is, you know exactly what's going on. She heard a woman being eaten alive in the middle of the night once because she couldn't defend herself.
