I just read of a new species of sea dragon that has been found in WA, where I currently am. Very similar to the weedy seadragon it has been found from DNA testing on museum specimens (the last collected in 2007) to be sufficiently different to be called a new species. Found at much deeper depths than weedy seadragons, with distinct red colouration, it is the first new seadragon to be found in over 100 years.
