Range DescriptionThis species occurs in the Red Sea and the Gulf of Aden, and the southwest and northern Indian Ocean.
The northern Red Sea from Rabigh to the Sinai Peninsula escaped most of the bleaching and the mortality of the last couple of decades. Destroyed and critical reefs are only 6% of the total (Wilkinson, 2004) because of its high latitude and very deep water extending close to shore, and wind induced upwelling. If these factors continue they are likely to contribute to survival of northern Red Sea species into the future. The southern Red Sea did not escape recent bleaching events and the Gulf of Aqaba and the Hurghada regions are affected by numerous direct impacts from coastal development and industry.
Genetics studies have, however, demonstrated the wide degree of differentiation of Red Sea populations from other Indian Ocean and Indo-West Pacific populations, consistent with a low level of gene exchange between the Red Sea and elsewhere. This relative isolation means that recovery following regional scale disturbance that decimates populations in the Red Sea may be compromised. For Red Sea endemics such disturbances would prove catastrophic.
