On the cover
The colour contrast in this photo is spectacular, but sadly, the reason for it is not. A bleached sea anemone glows white against an eastern clown anemonefish ( Amphiprion percula) on the Great Barrier Reef’s Osprey Reef in this Bob Halstead ( oceanwideimages.com) photo. Like corals, anemones bleach in response to elevated sea temperatures. See p52 for more.
