>what exactly is the physical mechanism that would cause instant death from 100°C water I honestly don't know. I just know I chucked a yabby (small crayfish) in a pot and it died instantly. Larger ones might take a tiny bit longer, but I'd be really surprised if it were more than three minutes. They're basically ready to eat by then.
