Here I believe is a triangulate household spider (Steatoda triangulosa) still munching away on her prize crab delight. She was in the same spot in my studio for three evenings in a row either guarding or eating her catch. And then someone did not clean up after themselves after they ate on my plant table. Canon 100mm macro, handheld, comments for improvement welcomed.

The blahs, yuch factor disappears when you watch one of these in action. A spider with a pencil dot size body can overcome something the size of a large Crainfly.
The poison acts fast to paralyze the victim. The spider will feed on the same body for over a week.
This leads me to believe the prey is not dead. Only paralyzed. Helpless.

Spider venom can certainly have more than one action. One essential action is that it liquifies tissue since spiders only feed on liquids and not solids. The liquified tissue is drawn in, but not thru its fangs -- those are only for injecting. They have a mouth behind the fangs that is flanked by some plates with bristles. I suppose the liquified food is drawn in between the plates by capillary action. Liquification probably takes place over an extended time, so they can come back over a period of days and have some more 'bug juice' to imbibe. Mmmm-mmm-mm.
I had a pet tarantula long ago, and I would feed her large grasshoppers and crickets. After she was done with them, what was left was pretty well mashed up (spiders can 'chew' with their chelicerae), and very light weight. I could carefully un-wad them and stretch them back out, and by this I found that what was left was pretty much just the shell. Even the head capsule and the legs, which were not crushed at all, were surprisingly hollow. It appears their internal soft tissues had been slowly extracted, leaving the undigestible parts behind.
