But in the ensuing decades, researchers realized that the larger dolphins were found primarily in offshore waters, whereas the smaller dolphins were found mainly in semi-enclosed bodies of water.

Burrunan dolphin (Tursiops australis) The Burrunan dolphin (Tursiops australis) was formally described as a new and separate species in 2011 by MMFs Founding Director Dr Kate Robb (Charlton-Robb) and colleagues, based on multiple lines of genetic and morphological evidence.

"This is an incredibly fascinating discovery as there have only been three new dolphin species formally described and recognised since the late 1800s," Ms Charlton-Robb said.

The Burrunan dolphin (Tursiops australis) is a species of bottlenose dolphin found in parts of Victoria, Australia. [1] It was recognised as a species in 2011. Though the species classification is contested by some, [2] a larger body of evidence now exists, further validating the Burrunan as a separate species to the common and Indo-Pacific bottlenose dolphins ( T. truncatus and T. aduncus , respectively).
