lobster question

so, you guys know how i feel about lobsters, right? I was watching swingtown the other night and somebody said that lobsters grow a pound a year, and that lobsters can live to be 40 years old. now, i didn't really verify this, so i don't know if it's true -- i don't know anything about sea creatures -- however, if it is, does that mean there are some 40 year old 40 lb lobsters hanging around somewhere? i swear to god, if i ever came face to face with one of those--- i can't even think about this. oh man, i hope giant snakes never enter that nightmare. oh shit.
