Last April, Greg Rouse, a marine biologist at the Scripps Institution of Oceanography in San Diego, and his colleagues embarked on a treasure hunt for the ruby sea dragon in the waters surrounding the Recherche Archipelago in Western Australia. Using a remotely operated underwater vehicle, the team spent several days scouring below for the fish.
