River dolphins

River dolphins are freshwater dolphins adapted to living in rivers and lakes, primarily found in South and Southeast Asia, and South America. Unlike ocean dolphins, they often have elongated beaks and flexible bodies suited for navigating shallow, murky waters. They have developed features like reduced eyesight and heightened echolocation abilities to hunt and communicate in their often cloudy environments. Due to habitat loss, pollution, and human activity, many river dolphin species are critically endangered, making their conservation vital for maintaining aquatic biodiversity and healthy river ecosystems.
