freshwater dolphins

Freshwater dolphins are cetaceans that live in rivers and lakes rather than oceans, found in major river systems including the Amazon, Ganges, Indus, and Yangtze.

Unlike their marine cousins, they typically have longer snouts, flexible necks, and reduced eyesight—adaptations for navigating murky waters and hunting fish in confined spaces.

Most freshwater dolphin species are critically endangered due to pollution, dam construction, and fishing nets.

The Amazon river dolphin, also called the pink dolphin, is the largest freshwater dolphin species.
