A recent expedition by the National Geographic Society’s Pristine Seas team has led to the astonishing discovery of the world’s largest coral colony in the Solomon Islands, located in the southwest Pacific Ocean. The find, which occurred in October 2024, took place when cinematographer Manu San Félix explored what appeared to be an ordinary shipwreck but turned out to be an expansive coral formation. Measuring 112 by 105 feet, this colossal coral is larger than a blue whale and is even visible from space, showcasing the scale of this underwater marvel.
The lead scientist of the expedition, Molly Timmers, emphasized that this remarkable find was largely accidental, occurring just before the team’s planned move to another location. This coral colony, comprised of nearly a billion genetically identical polyps, represents the largest ever recorded. While the colony is currently healthy, there are rising concerns regarding threats to coral ecosystems, such as climate change and overfishing. The researchers are hopeful that this discovery will galvanize support for greater protective measures for marine habitats in the region.
Characterized as Pavona clavus, or shoulder blade coral, this species displays a mix of browns and various vibrant colors. Researchers estimate the colony’s age to be around 300 years, allowing it to witness numerous significant historical events over centuries. Despite its impressive resilience, it has endured the effects of ocean degradation, including increased pollution and warming waters, which put strain on coral health worldwide.
Amid escalating coral bleaching incidents—affecting 77% of reef areas between 2023 and 2024—the survival of this unique colony gives renewed hope for the resilience of marine ecosystems. Timmers has suggested that the coral’s fortunate location in deeper, cooler waters may contribute to its health and longevity.
The local community, acknowledging the significance of this discovery, has been advocating for stronger protections for their waters. Their informal conservation efforts have been in place for 14 years, but they are now seeking national recognition of their marine areas to ensure better safeguarding against environmental threats.
As experts warn of dire consequences from global warming, efforts to phase out fossil fuels and expand protected ocean areas to 30% are deemed critical. Currently, only 8.4% of oceans worldwide benefit from governmental protections. The unique discovery of this giant coral serves as a powerful call to action, underscoring the importance of preserving natural wonders and their ecosystems for future generations.
In light of the challenges facing global marine life, this finding not only highlights the beauty and wonder of corals but also inspires hope for continued conservation efforts. The resilience of this extraordinary coral colony reminds us of nature’s enduring strength, urging humanity to remember and protect our oceans and their inhabitants.
