Azul Cielo Acropora

The Azul Cielo Acropora is another extremely rare and unusual deepwater Acropora species. Branches have a delicate morphology that is very unique for Acropora. Branch ends are bright sky blue, while polyp tentacles are bright electric sky blue. These pigments appear to only require weak to moderate light levels under a 20,000 K to remain colorful. The blue pigments are less dense along branch stems. This gives the branch stems a purple color due to the blue and brown mixing together. Photo and text courtesy of Reeffarmers.
