Threat pose?

[Crone Returns]

Hi. I tried to look it up, but couldn't find it.
Do true spiders exhibit threat poses like Ts?

 

[Richard McJimsey]

Yes, some do.

 

[Crone Returns]

Yes, some do.

Thanks. NOW I remember P. fera and all its ilk do. I am assuming that all mygalamorphs have threat poses?

 

[wizentrop]

Yes.

Cool... have you met the Shuar Tribe, btw? And their exquisite shrunken heads?

Thanks! Now you got me traipsing all over the universe lol! The falls and windswept tree are the best IMHO. But the photo of the Big Mama's threat pose takes the prize for sending the hair on my head bristling!
I'll check more out later.

You must post pictures of the -- shrunken heads. Yikes.

I love to collect shrunken heads :-s

Unfortunately for me that tribe is located deep in the Amazon, and the place where I work is not that deep. But hey, I get to find cool animals. I'll take that any day.

I've observed the threat posture in:
Latrodectus Hesperus, cornered, almost out of her web, with egg sack present.
Several Nephila, when the web is disturbed and males are present
A couple of Lycosids south of San Diego
A salticid paired off against another male
A lynx spider facing off a crab spider
Never observed sparassid use the posture.

Definitely. Both my Macrothele gigas and my Ctenus red fang have threatened me. It's adorable.

Use watch the first few seconds.

Yes, my Hogna carolinensis gave me one the other day, it was pretty pissed off. It was almost bent all the way backwards with its front legs high in the air. This is just because I opened the lid. She was having a really bad day apparently.

Sorry for the duplicate post but I have an other example. Once in the work bathroom there was a woodlouse hunter. I tried to save it because I knew other workers would kill it. I took a piece of paper towel and tried to coax the spider onto it. It threw back a gnarly threat posture and its fangs were out. Eventually I got the spider onto the paper towel and released it outside.

Lol. No good dead goes unpunished.

Ok. Need more coffee.
That was no good deed etc etc.
But might work for zombies et al.

Haha, definitely. I never knew wolf spiders displayed threat postures that crazy, it almost reminded me of a Brazilian wandering spider.

 

[The Snark]

Conjecture. The threat pose is organic genetic similar to a dog snarling and baring it's teeth. Or a cat, hunched down, teeth bared, weight off center and one paw raised, ready to take a swipe.

 

[Ratmosphere]

Definitely! Imagine if a wolf spider hissed when it threw up a threat posture. That would be terrifying.

If you want to see a threat pose+hiss in an arachnid, get yourself some Acanthophrynus coronatus. Those things are big, bold, AND loud.

Jeeeeez @wizentrop! I looked up that evil beast. I first thought how cute! Then it turned into the obt of whips.
To be fair I'd act like that and worse if I was being poked like that.
