On Wednesday a South Korean aquarium in Seoul featured an underwater performance as part of celebrations to welcome the coming Christmas season.
A diver dressed as Santa swam with a school of more than 20,000 shiny silver sardines, feeding them as they moved about in different formations.
A white-spotted eagle ray was also part of the show.
Many visitors said they were pleased to catch the performance.
The aquarium said the underwater show began Saturday and will continue until Dec. 27, adding that it is performed three times a day during the week and twice a day over the weekend.
