Why do spiders die on their back with their legs bent it towards their body?
Answers:
the body ends up that way because the body is heavier than the legs..when they die they are most likely to be body up...but reflexes draw the legs in.....they dont have balance like that so they roll to their backs
cos i squashed them
The ones I kill don't. Their legs are flat and usually migrated onto their heads through sheer force
most of the ones I see are flat and squashed
dont know but i just witnessed a spider killing a fly and the fly was still alive as it was being wrapped up, can you imagine if there was something above us on the food chain that killed us that way sorry but i felt really sorry for the fly i know its nothing to do with your question
they wiggle their legs all the time while they are dying and eventually flip upside down and stop.
not all spiders die on their backs, the ones that do, do-so because when they die the muscles inside there exoskeleton contract making the spiders limbs curl and there-4 roll onto their backs
the reason is because its a defense mehanism for the arachnids to get on their backs when they feel threatened and "play dead", same with flies and cockroaches
Good question.
I hope you get a serious answer.
It could be their legs bend in because of the leg joints drying out after death and curling inwards.
As for dying on their backs, could be because in that position its the lower centre of gravity that keeps it upside down after being blown over by the wind.
They probably dont die lying on their backs.
But I'm only guessing.
maybe the pain is lesser and they dont suffer so much.
Actually, when a spider dies, it's on their tummies so to speak, with their legs curled under them. If you see one on it's back with the legs curled it may be in the process of shedding it's exoskeleton and this is how they do it. I would guess that if one is truly dead that way, they died while in the process of molting (shedding) their exoskeleton.
As the body is heavier than their legs so its gravity really.
