In May, a South Korean fisherman caught an octopus clinging with its tentacles to a porcelain plate.
When archaeologists searched the area, they found a 12th century shipwreck full of ancient artifacts.
The porcelain dates from the Goryeo dynasty, which ruled from the 10th to 14th century and is considered Korea's Age of Englightenment. Goryeo are regarded as perhaps the finest ever made.
The octopus must have been a connoisseur.
