'big butt spider' seems as good a name as any

could be... I just noticed the pill bug to the far left, that is one huge spider. I didn't know tarantulas extended that far north but they are definitely present (though rarely seen) in coastal areas of southern California. In the desert too, of course.

This doesn't look hairy enough to be a true theraphosid. My guess is that it's a female Calisoga longitarsis, which is a sizable mygalomorph that's pretty common in the Bay Area. How big was it and where did you find it?

Hi... the "butt" (abdomen?) was the size of a nickel and we saw it in Santa Cruz, in the UCSC Arboretum.

If it was that big then I think this is the one.

I am really tempted to put 'big butt spider' as one of the common names for this species... but I resisted.

Thanks for resisting. There are many spiders with some junk in the trunk, so it's not the best common name.

good point, it doesn't give 'credit' to other copious-abdomened spiders.
