This rare “Blue Dragon” is a sensational discovery that has been spotted on the coast of Australia recently. It’s the Glaucus Atlanticus, a small sea slug that really leaves us in reverence, particular because they are unusually spotted by humans. One of these alien-like specimens was caught on film after washing ashore in Queensland, Australia.
These sea slugs are pelagic: they float upside down on the surface tension of the water, where they are carried along by the winds and ocean currents. Glaucus atlanticus is camouflaged: the blue side of their body faces upwards, blending in with the blue of the water. The silver/grey side of the sea slugs faces downwards, blending in with the silvery surface of the sea.
