Yangtze finless porpoise (Neophocaena asiaeorientalis)

Can finless porpoise live in freshwater areas? I thought this species only lived in the ocean.

The Indo-Pacific finless porpoise is exclusively a marine species. In contrast, the narrow-ridged finless porpoise is capable of inhabiting freshwater environments, and its freshwater populations are now frequently recognized as a distinct species.
