During an expedition in October 2024, a team from the National Geographic Society’s Pristine Seas discovered the largest coral colony in the world off the coast of the Solomon Islands. Initially mistaken for a shipwreck, the colony measures 112 by 105 feet, making it even longer than a blue whale. This colossal structure is so substantial that it can be seen from outer space, yet it had remained unnoticed by researchers until a serendipitous dive revealed its presence just before the team was set to explore another area.
The colony, named Pavona clavus or shoulder blade coral due to its unique shape, is composed of nearly a billion genetically identical coral polyps, functioning together as a single organism. Despite its impressive size and health, researchers voiced concerns about the threats facing corals globally, including climate change and overfishing. The discovery of this mega coral serves as a beacon of hope, prompting discussions about enhancing protections for marine environments in the Solomon Islands.
Notably, this coral colony is estimated to be around 300 years old and has survived significant historical moments, including the signing of the Declaration of Independence and the Second World War. Its resilience amidst the challenges posed by environmental changes emphasizes the interconnectedness of nature and history.
The research team noted that the coral’s habitat—situated in deeper, cooler waters—may be contributing to its health, suggesting that certain locations could be vital for coral survival amid rising temperatures. As 77 percent of coral reef areas experienced harmful bleaching in recent years, the sustained health of this impressive colony inspires hope for the future resilience of coral ecosystems.
Community leaders in the Solomon Islands are eager to leverage this discovery to bolster conservation efforts and secure protections for their waters, which have been informally safeguarded for the past 14 years. The findings underline the urgency for global action to combat climate change and protect marine biodiversity, with only a small percentage of the ocean currently under governmental protection.
Ultimately, the find embodies a powerful reminder that against a backdrop of ecological concern, there are still wonders to be discovered, emphasizing the need to remember and protect our planet’s rich marine life.
