Neophocaena phocaenoides lives in both fresh and salt water habitats. It is found in shallow coastal waters such as the Sea of Japan as well as fresh water rivers like the Yangtze river in China. Neophocaena phocaenoides is occasionaly found in inland lakes which have been cut off from the ocean but are still salt water. Neophocaena phocaenoides seems to prefer rocky promonotories and strong currents (Ganslosser 1988).
