River dolphins are unique aquatic mammals found in freshwater rivers and lakes, primarily in regions like the Amazon River and the Ganges River. Unlike their oceanic relatives, these dolphins have adapted to life in murky waters, developing a more elongated snout and a flexible body. They are known for their playful behavior and can often be seen leaping out of the water. These dolphins are crucial to their ecosystems, helping to maintain the balance of aquatic life. Unfortunately, river dolphins face threats from habitat loss, pollution, and fishing practices. Conservation efforts are essential to protect these remarkable creatures and their habitats.
