The dolphin genus Sotalia is considered to have two member species with the classification of Sotalia guianensis^[3]^[4] as a distinct species from Sotalia fluviatilis^[5]^[6] in 2007. This was a result of recent morphometric analyses, as well as mitochondrial DNA analysis.^[7]

Members of this genus are found in the Atlantic and Caribbean coasts of Central and South America as well as in the Amazon River and most of its tributaries.^[4]
