During an expedition in October 2024, the National Geographic Society’s Pristine Seas team made a remarkable discovery in the Solomon Islands—what is believed to be the world’s largest coral colony. The discovery, which occurred during a routine underwater exploration, revealed a massive colony measuring 112 by 105 feet, surpassing the size of a blue whale and even visible from space.
Cinematographer Manu San Félix initially thought he had stumbled upon a shipwreck. However, upon closer inspection, he identified the sprawling expanse of coral, leading to excitement among the researchers. Estimated to consist of nearly one billion genetically identical polyps, this colony of Pavona clavus, commonly referred to as shoulder blade coral, is primarily brown with vibrant patches of yellow, red, pink, and blue.
Despite its impressive health, researchers are concerned about the broader threats to coral ecosystems, such as global warming and overfishing. The team hopes that this discovery will spur increased protective measures for marine habitats within the Solomon Islands, which are part of the Coral Triangle, renowned for its rich biodiversity.
This coral colony, which stands about 16 feet tall and is approximately 300 years old, has survived through significant historical events, witnessing changes in the ocean environment caused by human activities and climate change. Researchers stress that while this colony is a remarkable specimen, many nearby reefs have already declined significantly.
The expedition leader, Molly Timmers, expressed optimism that the conditions surrounding this colony—being positioned in deeper, cooler waters—play a role in its robust health. This discovery serves as a reminder of the resilience of marine life, even in the face of global environmental challenges.
The researchers hope that the local community’s long-standing efforts to protect these waters will receive official recognition and support, emphasizing the need for greater marine conservation initiatives. Enric Sala, the founder of Pristine Seas, highlighted the urgency of protecting critical habitats around the world, advocating for the cessation of fossil fuel use and the establishment of protected marine areas.
This astonishing find not only inspires awe but also raises hope for the preservation of coral reefs amidst pressing environmental issues.
In summary, the discovery of the world’s largest coral colony not only showcases the wonders of the ocean but also underlines the importance of conservation efforts, reminding us of the fragile balance within our marine ecosystems. The ongoing commitment by local communities and researchers can play a crucial role in safeguarding the future of such important natural treasures.
