What is the term for living or growing in water?

The term "aquatic" specifically refers to organisms that live or grow in water, encompassing both freshwater and marine environments. Aquatic life includes a diverse range of organisms, such as fish, amphibians, aquatic plants, and microorganisms, all of which have adaptations that allow them to thrive in various water conditions.

While "marine" pertains specifically to oceanic environments, and "wetland" refers to specific areas where water covers the soil or is present near the surface, "aquatic" is a broader term that captures all forms of life associated with water, regardless of the type it resides in. "Terrestrial," on the other hand, describes organisms that live on land, making it unrelated to aquatic life.

Thus, "aquatic" is the most comprehensive and accurate term for organisms that are adapted to living or growing in water.
