The diver headed into the coral reef exhibit while dozens of children watched from behind the glass.

Volunteer diver George Bell wore his full Santa suit - from hat to coal black boots - and scuba gear for a recent feed. The show - known as 'Scuba Santa' - runs daily through to Christmas Day. It takes place during the morning feed at the Philippine Coral Reef tank at the San Francisco museum.

The academy's Philippine Coral Reef tank has thousands of reef fish representing about 100 species. Those at home can watch Santa's appearance online by webcam.

Viewers are delighted that Santa Claus is making to time scuba dive and feed the fish during this busy period.
