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.

Underwater splitshot image of  mangrove forest.\n Mangroves are plants that can live in saltwater. These important plants not only create a refuge for a vast number of marine animals, birds and reptiles but also play an important role in countering coastal erosion. \n\nThe dense network of roots and branches retain sediments and create a natural barrier protecting coastal communities against the more and more frequent floodings and hurricanes. \n\nFurther, mangroves have the capacity to sequester up to 10 times more CO2 per area compared to other forest ecosystems. Therefore these habitats serve as a blue carbon sink.\n\nUnfortunately, destruction of these important habitats due to development currently happens on a large scale worldwide.
