School of tiny blue fish swimming around bleached coral

Once Colorful, Now Pale Corals.

In this footage, we can see a dense school of tiny, vibrant blue fish swimming energetically around a cluster of partially bleached coral. The coral displays patches of both healthy, tan coloration and pale, bleached areas, highlighting the effects of environmental stress. The fish dart around the coral's branches, creating a lively contrast with the stillness of the reef floor below. The background of the clip reveals a sandy seabed with scattered coral formations, visible in the clear water. The fish move in synchronized bursts, surrounding the coral structure, which stands prominently on a small rock base.

This high-quality footage captures large, bleached mounds of Acropora finger corals in the clear ocean water, showing the critical condition of these reefs. Filmed in ultra-high-definition 4K and available in HD (1080p), this footage was shot with professional-grade equipment to highlight the detailed textures and colors of these vulnerable corals. Provided as free stock footage to raise awareness about coral bleaching, this video is available in both landscape (16:9 aspect ratio) and vertical (9:16 aspect ratio) formats, making it suitable for platforms like Instagram Reels, Facebook, TikTok, YouTube Shorts, and widescreen presentations. This versatility and clarity make it ideal for environmental campaigns, NGO projects, documentaries, and educational materials focused on marine conservation.

Here’s a fun fact about coral bleaching: coral reefs cover less than 0.1% of the ocean floor but support around 25% of all marine species. This makes them some of the most biologically diverse ecosystems on Earth, essential for the health of marine biodiversity and for the livelihoods of millions of people who rely on them for fishing and tourism. Because of their dependence on specific environmental conditions, however, corals are highly vulnerable to stressors like increased water temperature and pollution. Interestingly, NASA’s “CORAL” project uses high-tech imaging from aircraft to monitor coral health remotely. This technology helps scientists identify early bleaching signs from the air, allowing for faster responses and more effective coral preservation efforts.
