Freshwater cetaceans

Freshwater cetaceans are species of whales and dolphins that live exclusively or primarily in rivers and lakes rather than oceans. Examples include the Amazonian boto (pink river dolphin) and the Yangtze River dolphin. These animals have adapted to freshwater environments, often exhibiting unique features like elongated beaks or different body shapes. They face threats from habitat loss, pollution, and human activities such as dam construction. Despite their differences from marine cetaceans, they share similar behaviors such as complex communication, social structures, and echolocation, which they use for navigation and hunting in their freshwater habitats.
