Epic Underwater Nature: Shoal of Indian Dascyllus (Dascyllus carneus) on Fragile Coral Reef Ecosystem Ocean Environment. - stock video

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 Indian Dascyllus (Dascyllus carneus) and Dascyllus (Dascyllus trimacultus). They are using the reef as a natural protection from predators, this is a form of symbiotic relationship. 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, disease and pollution. The location is Ko Haa Archipelago, Andaman Sea, Ko Lanta, Krabi, Thailand.
