The Indo-Pacific finless porpoise (Neophocaena phocaenoides), or finless porpoise, is one of seven porpoise species. Most of the population has been found around the Korean peninsula in the Yellow and East China Seas, although a freshwater population is found around Jiuduansha near Shanghai at the mouth of China's Yangtze River. Genetic studies indicate that the finless porpoise is the most basal living member of the porpoise family.[2]

There is a degree of taxonomic uncertainty surrounding the species, with the N. p. phocaenoides subspecies perhaps representing a different species from N. p. sunameri and N. p. asiaeorientalis, currently reclassified as the narrow-ridged finless porpoise. Order: Artiodactyla, Infraorder: Cetacea. Family: Phocoenidae, Genus: Neophocaena, Species: Neophocaena phocaenoides (G. Cuvier, 1829).
