Can anyone identify this spider ?
I've lived in the Bay Area for about ten years after moving here from England and this is the biggest, ugliest spider I've ever had the misfortune to encounter. He'd walked up our Nannies trouser leg, and being the brave soul she is she managed to get him in my sons bug cage. He'd had met the bottom of my boot if he'd climbed up mine. Shudder. Anyway, what is it? From my research looks like a Funnel Web but I'm no expert, not dangerous is it?

Pic here. Judging by the shape, it's probably a female. It'll give you a hell of a bite if you piss it off, but it's not poisonous in any meaningful way. And yes, they are related to funnel-web spiders.

To be honest I've never seen one here in the Bay Area, but they're all over the place inland and down south about 400 miles. I wouldnt be at all surprised to learn that there's a Bay tarantula, especially in the San Jose area, but you've probably got someone's escaped pet.

Yes, there are tarantulas in the Bay Area, especially in the East Bay and South Bay hills. In fact, every fall, Henry Coe State Park (a huge state park/wilderness area east of Gilroy) has a TarantulaFest to celebrate the hairy critters.

Best answer: Your profile says that you live in Oakland, where true tarantulas are very infrequently seen but where Calisoga longitarsus pops up frequently in homes, especially up in the hills. The differences are subtle, and nothing in the pictures strongly diagnoses it, but I'm inclined to call it for Calisoga. Not quite linebacker-y enought to a tarantula, but then your pics are mostly leg. Calisoga goes by the common names "calisoga spider," and "false tarantula."
That animal is totally incredibly indoobitably male, in the last picture you can see the modifications to the palps (smaller "legs" all the way in the front) for sperm transfer.
For those keeping score, Calisoga is in the Nemesiidae, whereas tarantulas are the Theraphosidae, both are in the Mygalomorphae. For those keeping score obsessively, some name cops believe that it should still be called Brachythele longitarsus.
True tarantulas pop up alot over the hills in Contra Costa County [on preview, and over the hills in Alameda County, such as luriete's third link], often in pool filters, and famously on Mt. Diablo where males anually clog the roads in the fall and usually get on at least one of the local news broadcasts [on preview, and in print, such as luriete's second link]. Less frequently they pop up on the peninsula. There are natives (genus Avicularia), most pets are tropical and/or desert species and an escapee would likely die a swift but miserable death in this weather before being found.

And no, not dangerous. We californians need fear only the black widow. A bite would hurt tho.

Response by poster: Sorry, it's not 6-8 inches long, much smaller, perhaps 2-3 inches when it extends it's legs. Lower part of the abdomen is about as large as your thumbnail give or take, there was some red underneath it, and yes we live in the Oakland Hills, although after seeing this guy it might be time to move :)

Response by poster: I'm thinking Calisoga too, body length is about 1", much smaller than a tarantula. How far away would I need to take it so that it couldn't find its way back here :) Also are they likely to be others lurking around.

Weird, I live in Mt. Diablo's shadow (literally) and I've never seen a tarantula hereabouts. I need to leave the apartment a bit more, obviously.
