Tropicana Field is the world's only professional sports facility that features live cownose rays. The Rays Tank presented by VisitStPeteClearwater.com opened in 2006, and is located just behind the right center field wall. Through a unique partnership with the Florida Aquarium, there are over 30 rays that fans can touch and feed throughout the game. The 10,000 gallon tank is one of the ten-largest in the United States.
