River dolphins are a group of aquatic mammals that belong to the family Iniidae and Platanistidae. They are characterized by their long, slender bodies, a distinctive long beak-like snout, and a rounded forehead. River dolphins are typically found in freshwater rivers and estuaries in parts of South America and South Asia. They are known for their unique adaptations to their freshwater habitats, including flexible necks and flippers that allow them to navigate through shallow waters. River dolphins are carnivorous, feeding on fish, crustaceans, and other small aquatic animals. These highly intelligent and social animals are known for their playful behavior and are considered an important indicator of the health of their freshwater ecosystems.
