Bleached Coeloseris, Acropora, and fire corals in clear sea water

Vanishing Beauty: Bleached Coral Footage.

This underwater shot highlights a scene of bleached coral species, including a large Coeloseris coral in the foreground, along with Acropora and fire corals scattered throughout the frame. The Coeloseris coral stands out with its smooth, rounded structure and pale white color. It rests on a darker coral base, which adds contrast to its bleached appearance. The Acropora coral, visible behind it, has bleached white branches extending outward, while the fire coral presents with patches of light brown and white. In the clear blue water in this video clip we can spot a small, yellow-colored snapper fish swimming with other chromis fish near the Coeloseris coral, adding movement to the scene.

The Coeloseris coral is recognized for its distinctive dome shape and smooth, rounded ridges that resemble brain patterns. These patterns typically appear in a range of colors from soft browns to subtle greens, adding to the coral’s natural beauty and appeal as a foundational reef species. However, the bleached Coeloseris in this footage displays a stark white hue, a result of coral bleaching triggered by environmental stressors like warming sea temperatures. Bleaching occurs when Coeloseris coral expels its symbiotic algae, zooxanthellae, which not only give the coral its natural color but also provide essential nutrients through photosynthesis.
