Do Dolphins live in Rivers?

We probably heard that dolphins live in the ocean. But do they live in rivers? To find out please continue reading.

River dolphins are a widely distributed group of fully aquatic mammals that reside exclusively in freshwater or brackish water. They are an informal grouping of dolphins, which is a paraphyletic group within the infraorder Cetacea. The river dolphins comprise the extant families Platanistidae (the Indian dolphins), Iniidae (the Amazonian dolphins), and Pontoporiidae (the brackish dolphins). There are five extant species of river dolphins, and two subspecies. River dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla, with even-toed ungulates, and their closest living relatives the hippopotamuses, having diverged about 40 million years ago.ddddd



River dolphins are rarely kept in captivity; breeding success has been poor and the animals often die within a few months of capture. As of 2015, there are only three river dolphins in captivity.





  1. I can not believe that hippopotamuses are dolphins closest living relatives. Hippopotamuses are terrestrials and dolphins aquatic animals.Dolphins are my favorite animals because they are intelligent and there are pink dolphins in Amazon river.After reading this article i prefer river dolphins more because they have more fascinating features like no blubber.
