David has been diving here for more than 30 years. His images show coral ‘through the lens of time and climate change’ and are likely to become records of a vanished world.
Coral colonies are formed by thousands of tiny animals called polyps, each secreting calcium carbonate to build its own home. Polyps are fuelled by food produced by the algae living within their cells. When corals are stressed by overheating they become bleached, expelling their algae and turning white.
