I know that I've made several negative comments in regards to the Dallas World Aquarium, but overall I'd still rank it as the 15th best aquarium out of the 41 that I've been to in the United States and Canada. There is an overwhelming sense of amazement from a visitor's perspective, but the glass tank with a jaguar within it sums up what is wrong on so many levels with the larger animals at the facility. There is an upper deck behind the scenes, but do the jaguar(s) rotate with ocelots part of the time? Did the proposed jaguar exhibit expansion ever happen?
