Had a bit of an unusual experience with our donated arachnid (rosehair) this past weekend - had the lil girl out while I was checking around her cage, refilling water etc and she was quite content to be hanging out - the wife and kids never thought I'd hold her lol!

I was watching her walk around on my hand when i noticed she was kind of cocking her head up a little bit and bringing the fangs out. 'Surely not . . .' I thought - there was no movement on my behalf or anything that would have triggered a bite or even startled her - her posture wasn't aggrivated in the slightest - all legs on the ground . . . well on my skin at any rate.. She kind of dug into the skin a little with them, kind of in an exploratory pinch - almost felt like she was pulling herself forward using her fangs. Though I have not experienced one I venture to say it was not a full fledged bite, just felt like a few pinches.

After I put her back I noticed she'd drawn blood in 3 pairs of linear points but no irritation or anything.

Question for you seasoned keepers: was she just testing the flesh? do they pull themselves along on their fangs from time to time? will they bite unproboked or without signaling agitation through posture?
