What kind of spider is this? (picture included)?

Question

Don't give me ones that it looks "kind of like" I want to know exactly what this spider is and if it is harmful at all. Seen in Oregon on the coast. Go to http://greennature.com/gallery/spider-pictures/callobius_spider.html for a picture. Mine looked EXACTLY like this. But when I looked up the species this guy lists, they look nothing like it.... Hmm.

It's the FIRST picture on that page. Sorry = ]

Answer 1

Well, it says on the site that the first picture is a funnel web spider. If my deduction is correct, that type of funnel web spider is a hobo spider. Hobo spiders are venomous (poisonous) so they are dangerous.

Answer 2

Technically ALL spiders are poisonous; its a question if their fangs are big enough to puncture your skin. And any spider that CAN bite, has the potential of being dangerous because you could be allergic.
All spiders also have spinerettes, even the spiders who don't make a web. They'll use the webbing to wrap egg cases, or prey, or even lay a web 'line' to secure themselves while climbing walls.
Funnel web spiders, the real dangerous kind, are located in Austraillia. The ones in America are actually 'grass spiders', and rarely leave their webs that lay on top of grass or leaves, giving them a 'funnel' to crawl into to wait for prey.
In the US there are only 4 dangerous spiders:
Black widow, brown recluse, hobo spider, yellow sac spider.
But if your spider appears like the one in the photo, my best guess is a type of wolf spider. This is due to the stout body and the fact its not in a web, though the eye placement is important because they also identifies a wolf spider.
They have eight eyes arranged in three rows. The bottom row consists of four small eyes, the middle row has two very large eyes (which distinguishes them from the Pisauridae), and the top row has two medium-sized eyes.
As for the color, I'm wondering if the spider had just molted. They tend to be somewhat 'moist' at that point, or perhaps the spider is young? Without an actual picture, its difficult to tell

The top photo is a wierdly-colored picture that may be of Tegenaria domestica - one of the two US spiders called House Spiders. If it is, it should be brown instead of purply-black. The bottom picture is Tegenaria gigantea, the Giant House Spider. If you have that, then you almost certainly don't have to worry about Hobo Spiders, since gigantea eats agrestis at every opportunity. I don't off-hand know if coastal Oregon is in the known range of Hobos; there are a couple sites you can check, though - just do a search on Hobo Spiders, and you should find some that are up-to-date. As to ID, it's not easy for most of us to tell agrestis (potentially nasty bite) from domestica (harmless bite) just by sight, so you should get a spider person to check it out. Try your local University (Invertebrate Zoology department) or extension office for advice.

Answer 4

One rule you can always count in is this. If it moves slow
and doesn't try to escape when you agitate it, it is poison.
If it can move fast in flight then it is not poison. All spiders
have some venom. They use it to paralyze there pray. The
"daddy long legs" is very poison but with mouth parts too
small to be affective one people. The same apples to
snakes. If they are fast, try to catch it if you like. If it turns to
face you or is slow in crawling away he is best left alone.
Hope that helps. be careful.

Answer 5

it looks vaguely like a white tailed spider although i cant make out the 'white' patch on its bum. if the pic was taken in the US or Canada you can post it at bugguide.net and someone can help you there....
