Explanation
If it has to do with water, it's aquatic. If you prefer your volleyball net in a pool, it sounds like you're into aquatic sports. The word aquatic comes from the Latin word aqua, which means water. The adjective also describes something that takes place in water. If you are on a swimming or diving team, you can say you are into aquatic sports, which may take place at an aquatic center. If you visit an aquatic garden, you'll see plants that thrive in water like water lilies and lotus flowers.
