It started off as an old warehouse used for numerous businesses like Mohawk Rubber Co. and Tejano Rodeo. Now you know it as the Dallas World Aquarium, home to various underwater species. For only $18 (plus some tax) you get to feel like you are standing in the middle of a rain forest or getting the secret skinny about what really happens under the ocean's surface. Throughout the day they have feeding and performance times scheduled for almost everything from penguins to Orinoco crocodiles. Dallas World Aquarium also has a gift shop, bookstore and a few restaurants, if you feel like you need to take a break from the oceanic adventure. The best thing about this aquarium is that they're closed only on Thanksgiving and Christmas. So you can pick up and go whenever, except at night, because the animals need their rest too.
