If you reside in the United Kingdom, putting a live lobster straight into the pot may get you in trouble with the law.
Crustaceans have long been thought to have reflexes that do not induce internal suffering, implying that they are not genuinely aware of pain (as noted by Elwood 2019). A reflex is characterized by firing a small number of neurons, resulting in a rapid reaction to stimuli.
The neurotransmitters implicated in pain, on the other hand, are slower and linger behind the reflex response. This lag period is recognizable to anybody who has stubbed their toe and relished the few pain-free seconds before the tsunami of anguish arrives.
The 'pain' signal never reaches the brain in certain animals. Thus the reflex reaction is maintained distinct from a pain-induced reaction. The key difference is that, unlike a reflex, pain is felt in the brain rather than in the body.
