I looked up just as the water above me darkened. Within an arm’s length, a massive whale shark passed over my head, its tail methodically propelling it forward. I caught its improbably small eye looking intently at me as it glided past. Directly behind came a second whale shark and then another.
But I wasn’t swimming in the ocean – I was 30 feet below the surface, at the bottom of the 6.3 million gallon Ocean Voyager exhibit at the Georgia Aquarium. As a marine scientist, I’ve logged a lot of dives in places from tropical reefs to temperate kelp forests. But I’d never been this up close and personal with the world’s biggest fish. In the wild, whale sharks can grow to 40 feet and nearly 50,000 pounds; those at the Georgia Aquarium are a relatively “small” 25 feet in length.
