Underwater shot of the vivid coral reef at sunny day

The Red Sea is a rich and diverse ecosystem. More than 1200 species of fish have been recorded in the Red Sea, and around 10% of these are found nowhere else. This also includes 42 species of deepwater fish. The rich diversity is in part due to the 2,000 km (1,240 mi) of coral reef extending along its coastline; these fringing reefs are 5000–7000 years old and are largely formed of stony acropora and porites corals. The reefs form platforms and sometimes lagoons along the coast and occasional other features such as cylinders (such as the Blue Hole (Red Sea) at Dahab). These coastal reefs are also visited by pelagic species of Red Sea fish, including some of the 44 species of shark.

While the upper plateau of the famous Blue Corner reef at a depth of 10m hardly has any large corals (the storms are too strong at this exposed point), larger coral formations can survive at 17m. They offer shelter to several fish species. Blotcheye Solderfishes Myripristis berndti occurs in the Indo-Pacific and the Eastern Pacific in a depth range from 3 to 160m, feeds mainly on plankton such as crab larvae. Max. length 30cm, common 22cm. Common Bluestripe Snapper Lutjanus kasmira occurs throughout most of the Indo-Pacific region in a depth range from 2-265m, common length 25cm, max. 40cm. In daytime, this species forms nearly stationary schools and feeds individually by night on crustaceans and fishes. Blue Corner, Palau 7°8'3.65 N 134°13'10.52 E at 17m depth.

Look into the light, and the sky is white, not blue: the same phenomenon also occurs under water! \nThe rock overhang is fully encrusted with hydroids, ascidians, sponges and corals. Featherstars are sitting on top of the Acropora sp. table coral and on top at the left side, there is a Dwarf Hawkfish Cirrhitichthys falco. \nOrange Cup Coral Tubastraea coccinea occurs in tropical and subtropical Western Atlantic and Indo-Pacific in a depth range from 1-37m. \nAs the underside of the rock overhang is facing away from the sun, these specimen are feeding in full daytime. \nTriton Bay, West Papua Province, Indonesia\n3°54'50.604 S 134°6'0.828 E at 4m depth
