Sea World uses exaggerated behaviors or as many call it "tricks". (If you look again at the article in the manual you will see Trick listed as a buzzword- and replaced with Behavior.) The exciting behaviors of having a trainer ride on "Shamu's" back- take away from the look of stark tanks, the square sides, and un-natural features. (If you look at Vancouver Aquarium, you will see that rocks surround the tank itself but none are located in the tank itself. People may see these rocks thinking the park is doing it for the animal's sake- but if they where, wouldn't there be rocks IN the tank and not around?) The shows avoid talking at all in-depth educational material concerning marine mammal natural history, NATURAL RAW behaviors, or the bond between wild pod mates.(Source: "The case Against..."HSUS) According to the yearly averages of people going to parks, places like Sea World are convinced that people learn by simply walking through their turnstyles. Yet, this is elicited by mere exposure to live captive animals- this exposure does not translate into action or even awearness. Which is what the captive display industry states. (Source: "The Case Against..."HSUS) It is traditionally stated that parks like Sea World show to "educate". Yet videos, robots, etc. could successfully replace that.
