DOWNTOWN. "Moored" north of Centennial Olympic Park, a massive glass and steel prow beckons modern explorers to discover the wonders that lie deep within the Georgia Aquarium, one of the largest and most architecturally stunning facilities of its kind. Exotic batfish, sea goblins and bowmouth guitarfish are among 100,000 fish and marine animals patrolling the 6-plus million gallons of the deep water exhibit, which is home to the state's most prodigious residents ­ four whale sharks Alice and Trixie (Ralph and Norton passed in 2007); Taroko and Yushan joined the tanked in June 2007. A reality thanks to the generosity of Home Depot co-founder Bernie Marcus, the Georgia Aquarium has strong rescue, rehabilitation and education emphases and serves as one of the state's top special event venues.
