Sannakji Korea
Now that Japanese sushi is popular all over the world, many people are used to eating raw fish.
But this Korean delicacy is quite different, since the seafood isn't dead. Sannakji consists of baby octopuses which are sliced up while alive; the tentacles are still wriggling about when the dish is served. If you don't chew the octopus carefully, there's real danger that the tiny suction cups can stick to your mouth and throat and choke you.
