[Dentoid]

Interesting aside. I read that the zooxanthellae that are found within photosynthetic organisms are dinoflagellates that have shed their flagella when incorporated by the host. It was also theorized, in the article, that because we heavily skim our tanks bleached corals, clams, anemones etc may not be able to find the dinoflagellates, in our tanks, necessary to reincorporate them into their tissues.
