he said.
"Using that data, they believed that the ruby sea dragon lived at a depth of around 55 metres, about 30 metres deeper than its cousins.
It inhabits the coast of Western Australia. Phyllopteryx dewysea(ruby sea dragon): The ruby sea dragon was discovered in 2015. Using DNA and anatomical research tools, Scripps graduate student Josefin Stiller and marine biologists Nerida Wilson of the Western Australia Museum (WAM) and Greg Rouse of Scripps Oceanography found evidence for the new species while analyzing tissue samples supplied by WAM.
“We’re now in a golden age of taxonomy and these powerful DNA tools are making it possible for more new species than ever to be discovered,” said study co-author Greg Rouse of Scripps Oceanography. • Sea dragons are carnivores. The ruby seadragon (Phyllopteryx dewysea) is a marine fish in the family Syngnathidae, which also includes seahorses. Rouse told CBC News. • Only three types of sea dragons are known, with the newest one, the ruby sea dragon, having been discovered in 2015. Australian researchers have observed two specimens of a rare sea dragon that's never before been seen alive.Sea dragons aren't very common, found in the waters off the coast of southern Australia. A 3-D scan of the newly discovered Ruby Seadragon.
A specimen found on shore in 2007 was 23.5 cm (9.3 in) long. "And unbelievably, really, we found it. Then, in 2015, PhD student Josefin Stiller discovered that four samples collected over the years — the first in 1919 — had been misclassified as a common sea dragon. Even shallow waves make a big difference at that depth. "Who knows how many other smaller things or less spectacular things are down there waiting to be discovered?" Part of the reason the ruby sea dragon had been misclassified was because it was believed that the longer lobes had been broken off, leaving it with just stumps.Instead, the video showed that the ruby sea dragons' lobes were just that: stumps.As well, it wasn't clear why the fins behind the head were quite bulgy, with a lot more muscle than those of the other sea dragons. It is unknown if they developed this trait or if the other species lost it over time. On one particular day, the only thing the remote underwater camera could see was sand churned up by the moving water. The ocean didn't co-operate: rough seas plagued their expedition for the first two days.As water moves up from the Antarctic, it heavily influences the environment, Rouse said. For some time, only two types were known: the leafy sea dragon and the common sea dragon (sometimes also called the weedy sea dragon).Then, in 2015, PhD student Josefin Stiller discovered that four samples collected over the years — the first in 1919 — had been misclassified as a common sea dragon. They also decided to try for the ruby sea dragon, though they didn't hold out much hope. The ruby sea dragon resembles the common sea dragon in most respects, but it is red-colored. However, the video showed that, in the wild, their tails are actually curled. The team that discovered this species, named the marine fish after its color and they believe it is so red because it inhabits the deeper waters, where red hues are absorbed more efficiently and being red colored can help camouflage.In April 2016, researchers used an underwater camera to film a video of a live specimen for the first time, publishing their findings in January 2017.Based on records, many assumed that the ruby seadragon normally lives at depths beyond normal scuba range and diving limits, which may be the explanation to why it went undiscovered for so long.Scientific papers have been done by the University of Western Australia and Scripps Institution of Oceanography in San Diego.The ruby seadragon has a prehensile tail, which means it can use its tail to hold and manipulate objects. This species inhabits the coast of Western Australia. "I can tell you we did not really expect to find them," Rouse said. "When we find something spectacular like this, it's a sign there's a lot more to do. • Sea dragons are camouflaged to blend in with their environment. "Nicole has an avid interest in all things science. She found one that had washed ashore at Perth … "Incredibly, the team found not just one, but two — on the final day of the expedition.Seeing the ruby sea dragons in their natural habitat helped the researchers learn a lot more about them.Because the only known samples had washed up on shores, not much was known about the lobes, protrusions from their body.The common sea dragon has long, fleshy ones; those of the leafy sea dragons are even more elaborate.
