Scientists declared the ruby seadragon a new species in 2015, but that was based on dead specimens in a museum. Now though, Scripps Institution of Oceanography biologist Greg Rouse who led the team that originally discovered the species, managed to find two of the wonderful fish swimming around the Recherche Archipelago, off the south coast of Western Australia. Each one is about 10 feet long. Just kidding. They're 10 inches long. From National Geographic:
After four dives with a remote-controlled mini-submarine, they managed to film two ruby seadragons more than 167 feet underwater, as the fish swam through rocky gardens of sponges and nibbled at their prey, most likely tiny crustaceans called mysids...
...The footage confirms that ruby seadragons use a different means of camouflage than its closest relatives. Common and leafy seadragons are covered in leafy outgrowths meant to camouflage the fish as they swim through seagrasses. The ruby seadragon, however, lacks them—opting instead for a scarlet body, an efficient way to disguise itself from predators in the dark depths.
Most surprisingly, the video suggests that the ruby seadragon can use its curled tail to grasp objects.
