Corals are marine organisms in class Anthozoa of phylum Cnidaria typically living in compact colonies of many identical individual "polyps". The group includes the important reef builders that inhabit tropical oceans, which secrete calcium carbonate to form a hard skeleton.

A coral "head", which appears to be a single organism, is a colony of myriad genetically identical polyps. Each polyp is typically only a few millimeters in diameter. Over many generations, the colony secretes a skeleton that is characteristic of the species. Individual heads grow by asexual reproduction of individual polyps. Corals also breed sexually by spawning. Polyps of the same species release gametes simultaneously over a period of one to several nights around a full moon.
Corals are highly sensitive to environmental changes. Scientists have predicted over 50% of the world's coral reefs may be destroyed by 2030;[26] as a result most nations protect them through environmental laws.

Seaweed/algae can destroy a coral reef. In the Caribbean and tropical Pacific, direct contact between ~40 to 70% of common seaweeds and coral causes bleaching and death to the coral via transfer of lipid–soluble metabolites.[27] Seaweed and algae proliferate given adequate nutrients and limited grazing by herbivores. Corals die if surrounding water temperature changes by more than a degree or two beyond their normal range or if water salinity drops. In an early symptom of environmental stress, corals expel their zooxanthellae; without their symbiotic algae, coral tissues become colorless as they reveal the white of their calcium carbonate skeletons, an event known as coral bleaching.[28]

Many governments now prohibit removal of coral from reefs, and use education to inform their populations about reef protection and ecology. However, many other human activities damage reefs, including runoff, mooring, fishing, diving, mining and construction.
Local economies near major coral reefs benefit from an abundance of fish and other marine creatures as a food source. Reefs also provide recreational scuba diving and snorkeling tourism. Unfortunately, these activities can have deleterious effects, such as the destruction of coral. Coral is also useful as a protection against hurricanes and other extreme weather.

Coral reefs provide medical benefits for humans. Chemical compounds taken from corals are used in medicine for cancer, AIDS, pain, and other uses. Coral skeletons are also commonly used for bone grafting in humans.

Hello Foozi!
Another great pic with wonderful lightness. Great details and sharpness.It seems that you are an expert in underwater photos! Bravo, dear friend! Well done! TFS

Hi Foozi,

The underwater point of view is showing the details and colors of the corals and of the tropical fish. The presence of the fish has an effect of scale. The surrounding light is enhancing the colors. Have a nice day.

Hello Foozi,

Interesting pov on this nice coral. The light is a little bit too hard in my opinion and it is a pity that the tail of the fish touch the frame on the left.

Otherwise a nice picture and we don't see often underwater photos on TN.

TFS,

Michel

Preciosa Foozi, una fotografía que te transporta y que te hace soñar.
Un abrazo: Josep Ignasi.

great undewater scenery, greetings Ori

Hallo Foozi
I missed out on such a lot of wonderful, beautiful, unique photos the last couple of weeks and this Shallow Water coral of Perhentian Island, of yours being one. What a beautiful sight. So peaceful and relaxing to look at. The colours looks so pure and clean, the view of the underwater world such a pleasure to look at. To me the colours are magic, almost like the water in a swimming pool. Thanks for sharing, something different than the usual, but hey, your images are mostly something different than the usual and that is why I like them all so much. Thanks for sharing. Best regards.
Anna
