    Australian snubfin dolphins, Orcaella heinsohni, are native to Australian and Oriental coastal waters surrounding the Sahul shelf. They are found as far north as Manokwari, Indonesia and as far south as the Brisbane River in Australia. Their range in Australia is from Broome in Western Australia to Brisbane in Queensland.

     Australian Snubfin Dolphins, Orcaella heinsohni

     ... Description & Behavior

    Australian snubfin dolphins, Orcaella heinsohni (Beasley, Robertson & Arnold, 2005), are a recently recognized species of dolphin first described in 2005.

     ... They closely resemble and is closely related to Irrawaddy dolphins, and until they were described in 2005, they were thought to be Irrawaddy dolphins. However, Australian snubfin dolphins are three-colored, while the body of Irrawaddy dolphins only has two colors. Their skull and fins also differ slightly between the two species. ...

     ... Orcaella heinsohni

    In 2005 a new species of dolphin was found in Australian waters, the Australian snubfin dolphin. The discovery of a new mammal is extremely rare. Until recently the snubfin dolphin was thought to be an Irrawaddy dolphin, which is found in coastal areas and major rivers of south-east Asia, and is in serious decline. The snubfin dolphin is Australia’s only endemic dolphin, meaning it is unique to northern Australia. Coastal and river dolphins are among the most threatened species of mammal in the world.

    Snubfin dolphins, like all dolphin species, are toothed cetaceans and therefore have one blow hole and are generally smaller in size compared with the baleen cetaceans like the humpback whale. ...

    ... Australian Snubfin Dolphin

     ...  Description

    Australian snubfin dolphins produce broadband clicks, three different types of pulsed sound, and two different types of whistles to communicate with one another. During foraging, Australian snubfin dolphins produce click trains, which are also used to a lesser extent during socializing. During social behavior, Australian snubfin dolphins often produce squeak sounds. The two whistle types are both short in duration and relatively low in frequency (1 to 8 kHz) and occur during socialization and foraging. There is also evidence of ultrasonic sound communication among Australian snubfin dolphins. ...

     The Australian snubfin dolphin (Orcaella heinsohni) is a dolphin found off the northern coasts of Australia. It closely resembles the Irrawaddy dolphin (of the same genus, Orcaella) and was not described as a separate species until 2005. The closest relative to the genus Orcaella is the killer whale, Orcinus orca.[citation needed] The Australian snubfin has three colors on its skin, while the Irrawaddy dolphin only has two. The skull and the fins also show minor differences between the two species.


    The taxonomic specific name, heinsohni, was chosen in honor of George Heinsohn, an Australian biologist who worked at James Cook University, "for his pioneering work on northeast Australian odontocetes, including the collection and initial analysis of Orcaella heinsohni specimens which form the basis for much of our knowledge of the new species".[2] ...
