White, bleached fire corals and colorful fish over an undersea cliff

Ocean Corals After Climate Impact.

This footage showcases a striking view of bleached fire corals clinging to a steep undersea cliff, their pale, lacy branches standing out starkly against the intense blue water. The corals’ fan-like structures appear white and brittle, a clear indicator of bleaching, as they rise up from the rugged cliff surface. Surrounding the coral, colorful reef fish dart in and out of the branches, adding lively movement to the clip. These small fish, mostly orange Anthias, swim energetically over the undersea cliff which is textured with a mix of rocky formations and remnants of other coral species. Darker corals and patches of algae coat parts of the rock, adding layers of detail to the cliffside. The background of the shot reveals a wide expanse of deep blue ocean, giving the scene an open, almost vast feel as if extending endlessly beyond the video frame.

Ocean warming from climate change and greenhouse gas emissions is a serious threat to coral reefs. Small temperature increases—just 1–2°C above normal—can stress corals, including fire coral, causing coral bleaching. When temperatures rise, corals expel their algae, zooxanthellae, which provide nutrients and color. Without these algae, corals turn white and lose their energy source. Prolonged warm temperatures prevent corals from recovering, weakening their structures and increasing disease risk. In tropical and subtropical reefs, this damage can harm entire ecosystems. Healthy corals support many species, including colorful fish that rely on them for food and shelter.
