still to be identified. Scientists say the western Indian Ocean may contain as much coral biodiversity as Australia’s Great Barrier Reef, though not as much as the world’s richest region for corals, the so-called coral triangle in Southeast Asia. Reporting in the journal PLoS ONE
, David Obura, a scientist with the Group Coastal Oceans Research and Development in the Indian Ocean, said that 10 percent of the species are found only in the western Indian Ocean. He said the northern end of the Mozambique Channel, which sits between Madagascar and mainland Africa, contains roughly 250 to 300 coral species. Meanwhile, Australian scientists report that water temperatures around the Great Barrier Reef have increased steadily in the last 25 years
, in some places rising as much as .5 degrees C. Such increases can contribute to coral bleaching, which can lead to mass coral die-offs.
