It's a little known fact that the inspiration for the 80's blockbuster, Arachnophobia, was based on the largest and longest lived female spiders ever, the multonomak sucubai, commonly referred to as the "Portland Housespider".
What is absolutely fabulous about these creatures is that once they reach full maturity, around 8 years(google it), they achieve consciousness.
This time of year, if you are real quiet, you can hear them mating in the attic, but what's crazy is they know you are listening and it just turns them on.
