Fish swimming over colorful reefs with spots of bleached coral

A Colorless Symphony: Life Among Bleached Corals.

A sprawling reef filled with textured coral formations stretches across the footage frames, interspersed with noticeable patches of bleached, pale coral. The rich mix of coral species forms a layered landscape—some corals display vibrant hues of brown, yellow, and green, while others appear stark white, showing clear signs of bleaching. Fish of different colors and sizes weave above and around the corals which have diverse shapes, from rounded, bulbous structures to branching formations, each adding a unique texture to the reef bed. The clear, deep blue ocean in the background of this video clip enhances the reef's visibility.

Coral bleaching occurs in varying degrees, often categorized as partial and full bleaching. Partial bleaching affects only certain areas of a coral colony or reef, typically in response to short-term stress or minor temperature fluctuations. In these cases, only select coral polyps expel their symbiotic algae, zooxanthellae, resulting in white patches amidst otherwise healthy, colorful coral. In contrast, full bleaching impacts the entire coral colony or reef system. During prolonged periods of elevated water temperatures, pollutants, or sustained stress, the coral expels zooxanthellae across its entire structure, turning completely white.
