Genetics

Blue Dragon or Blue sea slug (Glaucus atlanticus) is an aeolid nudibranch which comes under the Phylum mollusca and family Glaucidae. These sea slugs are pelagic: they float upside down by using the surface tension of the water to stay up, where they are carried along by the winds and ocean currents. THis animal 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.
