Writhing, twitching, flexing and wriggling this lobster looks like he's having one hell of a bad day. And things are about to get much worse - for his prison is a dinner plate, and he's about to be served up to a table of hungry Americans.

Known as ikizukuri - which roughly translates as "prepared alive" - this controversial Japanese delicacy has divided food critics as to whether it is an important custom or just plain cruel.

SEE ALSO:

The live creatures are usually selected by customers from a sea-water tank, before being served up on a plate.

Fish is most commonly used in the practice, with octopus, shrimp and of course lobster, also being popular.

Bon appétit.

  • Raccoon

    I have had them a hundred times and it's only been delicious on a few occasions. Most folks don't understand that they have to be skinned well to remove all the fat, twice cooked (braise, then roast), and you need to remove the stink glands under the arms. If you don't, well, it gets pretty ripe.
