If you kill a venomous snake, note that they retain instinctive reflexes to bite for long after even their spinal cord is severed.
Jake Thomas, a volunteer who mows the local cemetery at Werris Creek, came across the snake, which he cut into half, during his usual clean-up but 45 minutes later, when he came back to get rid of the snake, it bit him twice…
Some reflexes may be retained for HOURS.
Recall this video of a decapitated snake that reacted and bit itself. It’s very bizarre.
Reflexive action after death may even happen to people on rare occasions.
