Michael Aldridge, general manager at Merlin Events, said it launched the experience in response to demand from guests who wanted to "put their chief executive in the tank".
Organisers booking an event at the aquarium can give two guests the chance to snorkel with the sharks. The names of the winners will be announced on the night via professional divers inside the shark tank, who will hold up their names during the drinks reception.
Being the fearless team we are, Event was eager to try it out first and sent news editor Rachel Bull into the water. Watch our video to see how she got on.
Would you be brave enough to enter the tank?
