Researchers have determined that dolphins found in southeastern Australia represent a previously unknown species.
Around 150 of the dolphins live around the Melbourne area and had until now been assumed to be one of the known bottlenose dolphins.
But detailed DNA studies and analysis of skulls in museums showed the two populations are in fact a new species.
The new classification as Tursiops australis is described in PLoS One.
The common name of Burrunan dolphins derives from the Aboriginal Australian for “large sea fish of the porpoise kind”.
Previous research had shown that the DNA found in the dolphins differed from that of the known bottlenose speciesTursiops truncatus and Tursiops aduncus.
But in order to define a new species, more evidence is needed. Kate Charlton-Robb of Monash University in Melbourne and her colleagues studied dolphin skulls found in a number of museums, as well as more detailed analysis of DNA, to show that T. australis is clearly a different animal.
“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. “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.”

Update: Chad Arment passes along that this may be locally called the Burrunan.
Loren Coleman is one of the world’s leading cryptozoologists, some say “the” leading. Certainly, he is acknowledged as the current living American researcher and writer who has most popularized cryptozoology in the late 20th and early 21st centuries. Starting his fieldwork and investigations in 1960, after traveling and trekking extensively in pursuit of cryptozoological mysteries, Coleman began writing to share his experiences in 1969. An honorary member of Ivan T. Sanderson’s Society for the Investigation of the Unexplained in the 1970s, Coleman has been bestowed with similar honorary memberships of the North Idaho College Cryptozoology Club in 1983, and in subsequent years, that of the British Columbia Scientific Cryptozoology Club, CryptoSafari International, and other international organizations. He was also a Life Member and Benefactor of the International Society of Cryptozoology (now-defunct). Loren Coleman’s daily blog, as a member of the Cryptomundo Team, served as an ongoing avenue of communication for the ever-growing body of cryptozoo news from 2005 through 2013.
