but no one has answered my questions

dolores, they can be cooked dead, of course. but the longer you leave them dead, the more the meat deteriorates and tastes gross.

some say its a good idea to sit the lobster in salt water for 15 mins to desensitise it, and the quickest way to kill it is to cut it in half, head first.

i always thought it was more humane to freeze them first, because they weaken quickly and die when exposed to extreme cold or heat, but tbh i don't really have much experience with lobster.

and what about the other seafood like octopus?? why aren't the cooked alive?

mussels are

yeah mussels definitely are, its unhealty to eat them otherwise. octopus, i have no idea. maybe the meat deteriorates at a slower rate or something, i'm sorry i don't know.
