It's a busy time for Santa Claus, but he's making time to feed some fish in San Francisco.
The California Academy of Sciences launched its holiday festivities Thursday by having a scuba diver dressed as St Nick submerge into a coral reef exhibit while dozens of children watched from behind the glass.
The "Scuba Santa" show runs through Christmas Day. It takes place during the morning feed at the Philippine Coral Reef tank at the San Francisco museum.
Volunteer diver George Bell donned his Santa suit, from hat to coal black boots, and scuba gear for a recent feed and fielded visitors' questions from inside the tank.
The Philippine Coral Reef tank has thousands of reef fish representing about 100 species.
People can watch Santa's appearance online by webcam.
Scuba diving isn't the only thing keeping Santa busy as he prepares for his sole work day for the year. (Isn't it funny how he works for one day a year but spends the rest of it judging you?) Check out some of the craziest versions and activities different Santa's have been getting up to across the world.
