ELI5: How can worms still move and be alive when cut in pieces?
gpt
They aren't alive for long. They have compartments, as you can see by the patterns on their bodies that look like rings, these compartments are separate from each other, but their organs are spread throughout the body, while the two halfs will writhe in pain, it is probable that both will die eventually, the same way as if you had been cut in half, your brain would remain lucid up until you died of blood loss, it just takes a bit longer for worms. They also don't use blood, they use hemolymph, which is the insect equivalent of blood.
