Neophocaena asiaeorientalisNeophocaena phocaenoidesNeophocaena sunameri Neophocaena is a genus of porpoise native to the Indian and Pacific oceans, as well as the freshwater habitats of the Yangtze River basin in China.

Genetic studies indicate that Neophocaena is the most basal living member of the porpoise family.

Instead there is a low ridge covered in thick skin bearing several lines of tiny tubercles.

The mean length at weaning was estimated to be 101 cm, corresponding to approximately 6 months of age.
