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

This stunning Staghorn coral ((Acropora cervicornis) is showing early signs of coral bleaching as the tips are turning white.  This is a critically endangered species of coral highly sensitive to pollution, climate change, ocean acidification and disease as its threats.  Coral reefs are some of the most diverse ecosystems in the world with 70% globally suffering coral bleaching.  The location is Phi Phi Islands, Andaman Sea, Krabi, Thailand.
Coral bleaching occurs when corals expel their symbiotic algae, known as zooxanthellae, due to stress caused by factors such as high water temperatures, pollution, or ocean acidification. This leads to the corals losing their vibrant colors and becoming pale or white. Without the zooxanthellae, the corals are more vulnerable to disease and may ultimately die. Coral bleaching is a major concern for coral reefs around the world, as it can have a devastating impact on the entire marine ecosystem that relies on these important structures.
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.
