"It has been 150 years since the last seadragon was described and all this time we thought that there were only two species," said marine biologist Nerida Wilson of WAM in the release. "Suddenly, there is a third species! If we can overlook such a charismatic new species for so long, we definitely have many more exciting discoveries awaiting us in the oceans."
A CT scan of the Ruby Seadragon revealed a different skeletal structure, confirming a new, third species.
There are about five Ruby Seadragon specimens in the world at this point, one of them from 1919, the press release said.
The researchers intend to mount a search expedition for more of the new species, probably deeper in the ocean than the other species, where its red color would help with camouflage in the dim light.
