Reef Madness: Key Found to Moonlight Spawning (2 of 2)

Caption: Corals like Acropora millepora spawn on one of a couple of nights each year. Biologists now track this synchronized ability to the presence of ancient cryptochromes molecules that are triggered by blue light. This image relates to an article that appeared in the Oct. 19, 2007 issue of the journal Science, published by AAAS. The study, by Dr. O. Levy and colleagues at University of Queensland in St. Lucia, QLD, Australia, was titled 'Light-Responsive Cryptochromes from a Simple Multicellular Animal, the Coral Acropora millepora.'
