In Korea, sannakji is a delicacy. However, not everyone would be too excited to eat it. Sannakji is raw, live octopus lightly seasoned and cut up. This can be tricky to eat because the tentacles may still be very sticky-sticking to the table, utensil, your teeth, tongue, or roof of your mouth. Other strange delicacies include snake wine in Vietnam, which is rice wine with a snake in the bottle; casu marzu, which is insect larva-filled cheese in Sardinia; balut, which is a developing duck embryo that is boiled and eaten in the shell in the Philippines; and more. Many exotic delicacies have been banned since being introduced because they are dangerous to eat.
