The sea, and air, have cooled dramatically beginning last week. The corals' stresses are changing. A disease that had ceased spreading on one individual in particular has reappeared or changed, and the coral will be completely dead soon.
I will post photos. My computer has given me some trouble lately, but I haven't lost any photos.
I'm wondering if the cyanobacteria, microorganisms, and algaes that attack corals are adversely affected by high temperauturs. This coral that I mentioned above seemed to have White Plague, but now it's attacked by a red growth.
In the meantime, here is another series, not dated, of damage to a coral when a fellow swimming over it very gently pushed himself off with his gloved fist. The first close-up is three days after the event, which was several years ago, film, not digital. I have newer photos to add. The coral was snow white and not recovering the last time I visited, about two weeks ago. The next time I post to you this page, it will download much more quickly, as I have since learned how to 'compress'. And the ease of viewing will be much improved.
