Coral polyps are naturally very pale in color, but corals come in a variety of bright colors. What gives coral its color?

    Yesterday was World Oceans Day and I watched some of the Google street-views, pretty amazing. I can't wait to read your next post and I will tell Ruben & Eli about it.

    I believe there are cyanobacteria that have some effect on the final color along with the symbiotic algae as well ,in some coral.
