Baby reef in shallow water on Red Sea / Lahami Bay. 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.

Yellow gorgonian (Eunicella cavolini) in the Mediterranean Sea
The color of Gorgonian Seafan Annella mollis varies and ranges from cream-colored to pink and orange. The close-meshed skeleton of the species in the family Subergorgiidae consists of fused sclerites and gorgonin, so it is extraordinarily flexible and thus perfectly adapted to strong currents. This white specimen, unusual for that region, is bleached. A lot of small fishes, mainly Anthias and Damselfishes are there. Palau, Micronesia, 6°59'10.52 N 134°13'7.34 E at 32m depth
