Lobster

Lobsters caught in Australian lobsters are spiny lobsters, sometimes called crayfish, but properly known as southern, western, eastern, and tropical rock lobsters. They differ from Atlantic lobsters in the absence of claws but are otherwise similar (if not superior) in the quality and characteristics of their flesh.
Normally sold live, cooked, or frozen, buying uncooked, chilled rock lobster is not advised, as it is hard to know how much time has passed since the lobster died. The RSPCA recommends live crustaceans be killed as humanely as possible, specifically by placing the animal in the refrigerator or freezer until it is asleep, and then killing it by splitting it or spiking it to destroy the nerve centres.
