Iniidae is a family of river dolphins containing one living genus, Inia, and four extinct genera. The extant genus inhabits the river basins of South America, but the family formerly had a wider presence across the Atlantic Ocean.
Iniidae are highly morphologically different from marine dolphins by way of adaptations suited to their freshwater riverine habitat.[1] They also display a high amount of sexual dimorphism in the form of color and size.[2] Seasonal movement between flooded plains and rivers is common, due to the variation of seasonal rain.[3] There has been little research done on the family, in particular the species aside from the Amazon river dolphin.[2]
