This video showcases coral bleaching, a clear sign of stress in corals caused by rising sea temperatures. Corals rely on microscopic algae called zooxanthellae for their color and up to 90% of their energy. Under stress, this symbiotic relationship breaks down, and the corals expel the algae, revealing their white skeletons.
Initially, stressed corals may display vibrant fluorescent hues in pink, yellow, or blue, but without zooxanthellae, they begin to starve. Captured using unique underwater macro time-lapse techniques, this footage offers an unparalleled look at the fragility of coral reefs and underscores the urgent need for their protection.
