phylum | Chordata | The finless porpoise (Neophocaena phocaenoides) is one of six porpoise species. It lives in the coastal waters of Asia, especially around Korea, India, China, Indonesia, Bangladesh and Japan. A freshwater population found in the Yangtze River in China is known locally as the jiangtun (江豚) or "river porpoise". In the waters around Japan, at the northern end of its range, it is known as the sunameri. The finless porpoise almost completely lacks a dorsal fin. Instead there is a low ridge covered in thick denticulated skin.
