Aquatic life refers to the diverse range of organisms that live in water environments, including oceans, rivers, lakes, and wetlands. This category includes various species such as fish, amphibians, crustaceans, and aquatic plants. These organisms have adapted to their watery habitats, developing unique features like gills for breathing underwater and streamlined bodies for efficient movement. The health of aquatic life is crucial for maintaining balanced ecosystems. Many species play essential roles in food chains, while others contribute to nutrient cycling. Human activities, such as pollution and overfishing, can threaten these ecosystems, impacting both aquatic organisms and the overall environment.
