Dallas World Aquarium

See the entire aquarium, but don't miss the Orinoco exhibit, which is a reproduction of the South American rain forest. This artificial habitat is an aviary with free-flying tropical birds such as toucans, but it also has on display Antillean manatees and electric eels. 21 bucks will buy an adult admission, but rest assured - your money is also going towards conservation efforts to preserve endangered species.
