All aquatic species, including fish and other aquatic animals, are uniquely adapted to a water life. All species are specially suited for the lives they lead. Humans are walkers with legs, allowing for effective movement on land. Mallards are fliers with wings, which allow them to move through the air. Bluegills are swimmers with fins enabling them to swim in water. An adaptation is a behavioral, structural, or physiological trait that increases a species’ chance of survival in a specific environment. Every living thing has adapted to fit with where it lives. That’s what it takes for life to survive. Aquatic organisms live in water and have adaptations to do so. — Texas Aquatic Science Chapter 4: Living in Water
