I'm glad you asked.
There happen to be two main criteria that most ethicists agree on for determining whether a living creature has the capacity to suffer and so has genuine interests that it may or may not be our moral duty to consider.
One is how much of the neurological hardware required for pain-experience the animal comes equipped with—nociceptors, prostaglandins, neuronal opioid receptors, etc.
The other criterion is whether the animal demonstrates behavior associated with pain. And it takes a lot of intellectual gymnastics and behaviorist hairsplitting not to see struggling, thrashing, and lid-clattering as just such pain-behavior.
Have you ever boiled a live lobster? Struggling? Thrashing? Lid clattering? None of that occurs. They react when I pick them up, it doesn't matter where I bring them. When I gently place them in a pot that they fit in, they do nothing. They might move a little, but nothing like you describe.
I am not saying they do not feel pain, I am not saying that boiling them is ethical. What I am saying is that people like you bring up false statements using words like "thrashing" and "struggling" to make your point. Instead of making false truths just be honest. You don't think it's ethical, okay.
Now I've boiled literally hundreds of lobsters in the 30+ years I've lived in Maine, so please spare me any Wikipedia or other biased articles telling me about how much they "struggle to survive" when boiled.
And I hope all of you people show the same disgust when your children stomp on spiders and ants for no good reason. They are the same as a lobster, and most of us don't even eat them.
