Record-breaking Coral Discovered in Southwest Pacific

Scientists have identified the largest coral ever documented in the southwest Pacific Ocean. This colossal coral, described as a single organism formed by numerous interconnected, minute creatures rather than a reef, is estimated to be over 300 years old. The research team indicates its size surpasses that of a blue whale. The discovery was made by Manu San Felix, a videographer aboard a National Geographic vessel exploring secluded areas of the Pacific to assess the impacts of climate change. San Felix recounted, “I went diving in a place where the map said there was a shipwreck and then I saw something.” San Felix summoned his diving partner, his son Inigo, and together they descended deeper to examine the find. He described encountering the coral, located in the Solomon Islands, as akin to witnessing a “cathedral underwater.” He expressed, “It’s very emotional. I felt this huge respect for something that’s stayed in one place and survived for hundreds of years.” He further remarked, “I thought, ‘Wow, this was here when Napoleon was alive’.” Expedition scientists utilized an underwater tape measure to gauge the coral’s dimensions. It measures 34m in width, 32m in length, and 5.5m in height. Worldwide, coral populations are experiencing significant stress due to warming oceans, a consequence of climate change. Corals consist of hundreds of thousands of individual living organisms known as polyps, each possessing its own body and mouth, which collectively form a colony. Certain corals develop hard, external skeletons; when numerous such skeletons merge, they create a coral reef. Some reefs can span immense distances, establishing extensive formations that provide habitats for fish and various other species. The World Economic Forum states that coral reefs also support the livelihoods of one billion individuals, through activities such as tourism and fishing. This particular specimen was discovered in deeper waters compared to some coral reefs, a factor that potentially shielded it from elevated sea surface temperatures. The announcement of this discovery coincided with the UN climate talks COP29 in Baku, Azerbaijan, where efforts are underway to advance solutions for climate change. Mr. Trevor Manemahaga, the climate minister for the Solomon Islands attending the summit, informed BBC News that his country takes pride in the recently found coral. He stated, “We want the world to know that this is a special place and it needs to be protected.” He further emphasized, “We rely mostly on marine resources for economic survival so coral is very, very important […] And it’s very crucial and critical for our economy to make sure our coral is not exploited.” Small island nations, including the Solomon Islands, are highly susceptible to the impacts of climate change. Mr. Manemahaga reported witnessing the direct consequences of global warming on his nation, which manifests as more intense cyclones and coastal erosion leading to homes collapsing into the sea. Numerous developing countries participating in the talks are advocating for increased financial assistance from wealthier nations to fund their climate change mitigation strategies. Mr. Manemahaga indicated that additional funding for the Solomon Islands would enable the country to develop a broader range of employment opportunities, thereby reducing reliance on industries detrimental to coral reefs. Logging currently constitutes a significant portion of the nation’s economy—contributing between 50-70% of its annual export revenue—but it generates substantial water pollution that harms local coral. Eric Brown, a coral scientist participating in the National Geographic research expedition, observed that the coral’s health appeared “pretty good.” He commented, “While the nearby shallow reefs were degraded due to warmer seas, witnessing this large healthy coral oasis in slightly deeper waters is a beacon of hope.” Identified as the species Pavona clavus, the coral serves as a habitat for shrimp, crabs, fish, and other marine life. Its considerable age also offers insights into historical oceanic conditions. Scientists intend to study it to understand its growth patterns further. A report released this week by the International Union for the Conservation of Nature revealed that 44% of warm-water corals face extinction. This represents a one-third increase since the last assessment of these species in 2008.
