Freshwater Dolphins

Some people (Wanda!) didn't believe me when I said there were freshwater/river-dwelling dolphins. Well then, what is this?

River dolphins are four species of dolphin which reside in freshwater rivers and estuaries. They are classed in the Platanistoidea superfamily of cetaceans. Three species live in fresh water rivers. The fourth species, the La Plata Dolphin, lives in saltwater estuaries and the ocean. However it is scientifically classed in the river dolphin family rather than the oceanic dolphin family.

I rest my case.
