PARIS (Reuters) - Scientists have discovered a pristine, 3-km (1.8-mile) long reef of giant rose-shaped corals off the coast of Tahiti, in waters thought to be deep enough to protect it from the bleaching effects of the warming ocean.
The reef, which lies at depths of more than 30 metres (100 feet), probably took around 25 years to grow. Some of the rose-shaped corals measure more than 2 metres in diameter.
