In Japan, fish that are prepared for sashimi while still alive are called "ikizukuri." The fish is typically filleted without actually being killed and served while the heart is still beating and the mouth is still gasping. Sometimes the fish is temporarily returned to an aquarium to swim around and recover for a second course. Another dish, popular in China, is called "yin yang fish," in which the fish's body is rapidly deep-fried and served while the head is still fresh and moving. Need proof?
