San-nakji (산낙지) is a variety of hoe made with long arm octopus, a small octopus species called nakji in Korean and is sometimes translated into "baby octopus" due to its relatively small size compared to the giant octopus. The octopuses are most commonly killed before being cut into small pieces and served, with the nerve activity in the octopus' tentacles making the pieces move posthumously on the plate whilst served. The octopus' highly complex nervous system, with two-thirds of its neurons localised in the nerve cords of its arms, lets the octopus show a variety of reflex actions that persist even when they have no input from the brain. Less commonly, a live octopus is eaten whole. The dish is sprinkled with sesame oil and toasted sesame seeds.
