The Irrawaddy dolphin (Orcaella brevirostris) is a euryhaline species of oceanic dolphin found in discontinuous subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia. Genetically, the Irrawaddy dolphin is closely related to the killer whale (orca). It is also closely related to the Australian snubfin dolphin, and these two were only recently recognised as distinct species. The species name brevirostris comes from the Latin meaning short-beaked. In 2005, genetic analysis showed the Australian snubfin dolphin found at the coast of northern Australia forms a second species in the Orcaella genus. Order: Artiodactyla, Infraorder: Cetacea, Family: Delphinidae, Genus: Orcaella, Species: Orcaella brevirostris (Owen in Gray, 1866)
