Corals in the form of tentacles on a reef.
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.
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
