Purse Web Spider

I've always been interested in this species, though my range happens not to overlap its. I learned about it from books when I was a child, and was immediately fascinated by its habit of living inside a sort of silken sock. When an insect treads on the sock, the spider bites through the silk for the kill. Perhaps that's why the spider needs that massive set of chelicerae. 

Incidentally, the purse web spider is altogether more civilized about romance than certain widow spiders frequently mentioned here. Male and female often cohabit peacefully. It's only after the male dies of old age that the female eats him.
