經過十七年系統地檢視歷史紀錄、實體描述及駝背海豚共同資料,海洋生物學家認為一種遊弋於西非與北澳州海岸之間的物種為第四種獨特的駝背海豚,並命名為 The Australian humpback dolphin, Sousa sahulensis.

研究過程有趣的發現:

Another interesting finding with the designation of the Australian humpback dolphin is the support its distribution provides to a zoogeographical barrier described by Alfred Russell Wallace, one of the first naturalists to examine in detail the life of the Malay Archipelago. He identified a barrier now known as the Wallace Line. To the west of the line, terrestrial animal species are mostly of Asian origin; to the east, animal species largely descend from Australasian ancestors. Researchers have also found the Wallace Line to be a barrier for marine species as well, and the divide between Indo-Pacific and the Australian humpback dolphins seems to coincide with this border.
