I did find this link, but I don't think it will help out much, because there is nothing on the internet about it, other than this. http://en.allexperts.com/q/Wild-Animals-705/frozen-crab-life-thawed.htm. Or you can go to this link. Its about frozen lobsters coming back to life after thawed.
It will die before the water boils. When the water has reached boiling point, lower the heat and simmer the lobster for around 15 minutes for the first 450g.
