Conclusion The Dallas World Aquarium had many different organisms.

I enjoyed learning about all the different animals, espically the turtles. There are so many different organisms I did not even know

exsisted. There are many benifi ts of

having an Aquarium in our area. Almost every

single animal at the DWA are animals not found anywhere

in our area. The Jaguar for example is not located anywhere

close to Lewisville, TX and the DWA allows us to see one up close and personal.
