Here's what they look like, but the image has no size reference so who knows how big they get?

I can't tell if that's a Toyota or a Chevy in the first joint of the tentacle curved back into its mouth, but either way, yikes!

About 10mm.

I googled it to make sure they weren't in this area. Seems they aren't well suited to hot dry climate.

We have enough in Black Widows, Brown Recluse and scorpions (although the scorpions aren't poisonous).

Many years ago when I took geology in college the professor was always careful to place a rock hammer or other object of known size in any slide he took so the audience would know the real size of the formation that had been photographed. It definitely pays to to the same thing when photographing insects or arachnids.
