(WXIA) -- To travel to a different civilization, where oxygen is scarce and inhabitants seem alien, you don't need a spaceship. Instead, you need a steady air supply and an explorer's curiosity to go beneath the surface.
We're the guests below water, and the whale shark is the fearless king.
"You get close and realize, face to face with animals, they are truly majestic and not fearsome," said Chris Duncan with the Georgia Aquarium's Dive Immersion Program team.
Like any world leader, some are fierce. Others are misunderstood.
"Most of them have no interest in eating people at all," said Georgia Aquarium Director of Research and Conservation Dr. Alistair Dove.
The Georgia Aquarium is home to four whale sharks. Visitors can float beside them all.
"The largest fish in the ocean, right here in Atlanta, Georgia," Duncan said.
