If you have not been to the Georgia Aquarium, one of their largest attractions are the whale sharks like the one seen here. They have a viewing area that they call the WOW room where you can see these immense creatures swim by along with many other fish, sharks, rays and occasionally, divers. Whale shark is the largest of all fishes. You can really get the scale of how big this is by comparing to the diver in the lower center part of this shot.
The bubbles you see rising through the tank are other divers who were also there at the time. Part of the exhibit is to feed and care for the residents of the tank. They even have radios to talk with the divers while they are in the tank. It really is incredible to see this undersea world so close up.
