The Alliance of Marine Mammal Parks and Aquariums recently funded a study about guest perceptions of aquariums and zoos. Among their many questions, the study sought to find out which animal had the biggest appeal to American aquarium visitors. Dolphins came out on top with an outstanding 40% of the respondents naming them as their favorite. Sharks came in a distant second, and killer whales, much to the chagrin of SeaWorld, came in nearly last. Check out the study in more detail here.
