San-nakji (산낙지) is a variety of hoe (raw dish) made with long arm octopus (Octopus minor), 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 (Enteroctopus dofleini). 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.

Less commonly, a live octopus is eaten whole. The dish is sprinkled with sesame oil and toasted sesam
