New dolphin species discovered in Australia

Researchers in Australia have discovered that dolphin colonies living around Melbourne are a species unlike any other in the world, they revealed on Thursday.

Researchers in Australia have discovered that dolphin colonies living around Melbourne are a species unlike any other in the world, they revealed on Thursday.

The that frolic in Port Phillip Bay and the Gippsland Lakes, numbering around 150, were originally thought to be one of the two recognised bottlenose species.

But Monash University PhD researcher Kate Charlton-Robb found they were different by comparing , DNA and with specimens dating back to the early 1900s.

She has named them Tursiops australis, although they will commonly be known as the Burrunan dolphin, an Aboriginal name meaning large sea fish of the porpoise kind.

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

"What makes this even more exciting is this dolphin species has been living right under our noses, with only two known resident populations living in Port Phillip Bay and the Gippsland Lakes in Victoria state."

The research relied in part on the analysis of dolphin skulls collected and maintained by museums over the last century, particularly holdings at Museum Victoria.

LOL.

One wonders who to trust in the fields of historical geology, paleontology, and "evolutionary" biology.

After all, if something as large as a DOLPHIN can live near and AT the surface all this time and not even be recognized, I wonder how many presumed "extinct" aquatic life forms are really still alive somewhere?

Sorry I accidentally gave you a one instead of the spammer.

However I think your post was a bit wrong. The study was based on skulls which are kind of hard to see in a living animal AND it may be crap anyway as the article gave no indication of what the differences were.

Genetic testing would be rather a lot more definitive.

The article DID say they were tested genetically. Also shapes of the skull and physical traits. Three different avenues of research saying they are a different species.

Use the 'report abuse' option for spammers - one is too high of a score.

Ethelred - Read the article first before commenting. Of course you could also change your handle to "Ethelnotread" ;)

LOL @ people criticizing Ethelred. He's done more for this site than all of us put together. Not that he needs me to defend him, but on the DNA thing: he read it and he knows. There's no detail in this abstract or links to more info; that's what he's talking about ("no indication what the differences were"). Unlike some, he want's to learn, not be spoon-fed or troll. Sure, we trust that the info is somewhere, but in order to discuss this with any significance, we need to know, ourselves.
