Coral mortality in reefs is a well-known and common event. Even the healthiest reefs always contain some dead colonies among the coral aggregation. Since the aragonitic skeletons of hard corals remain intact long after the coral animal has died, they scarcely reveal the cause of their death. Coral mortality is easy to record but difficult to investigate. Hard corals can die from several reasons (tissue predation, epizootic and epiphytic suffocation, etc.). Recently, coral mortality by diseases seem to reveal yet another aspect and may well be related to worldwide anthropogenic impacts. This page highlights the photographic documentation of the field trips held in Aqaba (Jordan).
