Giant squid discovery uncovers a hidden deep-sea world off Australia

Scientists exploring deep underwater canyons off the coast of Western Australia uncovered a hidden world packed with bizarre and elusive marine life — including signs of the legendary giant squid. By analyzing traces of DNA floating in seawater from depths exceeding 4 kilometers, researchers identified 226 species ranging from deep-diving whales to strange fish rarely or never seen in the region before. Some of the creatures may even be unknown to science.
