The vast majority of the world is covered by oceans , and in those oceans are a lot of interesting creatures .

We’ve created aquariums to look at some of these amazing animals. Building an aquarium is no small feat. That’s why we’re going to identify and celebrate the 12 biggest aquariums in the U.S. That way, we can see how big we’ve managed to get these aquatic zones!

What Is An Aquarium?



An aquarium is best described as an artificial aquatic tank or series of tanks that house aquatic animals. Another way to put it would be the aquatic equivalent of a zoo. The idea is simple, but the execution is difficult. Water is heavy and difficult to store correctly. Also, not every sea creature can survive in the same area. Creating these artificial environments is difficult, so the biggest aquariums in the U.S. should be celebrated!
