Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species. Here we see a shallow coral reef consisting mainly of hard corals supporting shoals of Moorish Idol Fish (Zanclus cornutus). Its corals although on the whole healthy, are showing signs of distress. 75% of the worlds coral reefs are now classed as 'Threatened,' with 60% of most reefs having local damage from anchors, overfishing, coral bleaching (as seen here), disease and pollution.
