Scientists have discovered the world’s largest coral in the Solomon Islands, a remarkable find that offers a glimmer of hope amid growing concerns about marine ecosystem health. The mega coral, which is actually a collection of tiny connected creatures forming a single organism, is larger than a blue whale and could be over 300 years old.
The discovery was made by Manu San Felix, a videographer working on a National Geographic expedition exploring remote Pacific regions. While diving in an area marked for a potential shipwreck, he spotted something extraordinary. Describing the experience as seeing a “cathedral underwater,” San Felix was deeply moved by the coral’s longevity, remarking that it had existed since Napoleon’s time.
Scientists measured the coral meticulously underwater, finding it spans 34 meters wide, 32 meters long, and stands 5.5 meters high. The specimen, a species called Pavona clavus, provides a habitat for numerous marine creatures including shrimp, crabs, and fish.
Notably, this coral was found in deeper waters, which may have protected it from the higher surface temperatures threatening many coral ecosystems. Eric Brown, a coral scientist on the expedition, described the find as “a beacon of hope,” highlighting that while nearby shallow reefs were degraded, this coral remained healthy.
The discovery comes at a critical time for marine ecosystems. A recent report from the International Union for the Conservation of Nature revealed that 44% of corals in warm waters are now threatened with extinction – a significant increase from 2008.
Trevor Manemahaga, the Solomon Islands’ climate minister, emphasized the coral’s importance, stating that marine resources are crucial to the nation’s economic survival. He stressed the need to protect such unique marine environments, especially as small island nations like the Solomon Islands are extremely vulnerable to climate change.
The country currently faces significant environmental challenges, with logging contributing 50-70% of annual export revenue while causing water pollution that damages coral reefs. Manemahaga suggested that additional international financing could help develop more sustainable economic alternatives.
The coral’s extensive age also presents a scientific opportunity, potentially offering insights into historical oceanic conditions. Researchers hope to study its growth and survival mechanisms.
This discovery was strategically announced during the UN climate talks (COP29) in Baku, Azerbaijan, drawing attention to the critical state of marine ecosystems and the urgent need for conservation efforts.
The mega coral serves as a powerful symbol of resilience, surviving for centuries and offering hope in a time of significant environmental challenges. Its existence underscores the importance of protecting marine biodiversity and understanding the complex ecosystems that support life on our planet.
