What are aquatic animals?
Aquatic animals are animals that live in water, such as oceans, rivers, lakes, and ponds. They include a wide range of species, from small microscopic plankton to large marine mammals like whales and dolphins. Some aquatic animals are adapted to live in freshwater, while others live exclusively in saltwater.
