In the waters of the Solomon Islands, scientists have discovered the world’s largest known coral, a massive Pavona clavus visible even from space. With a circumference of 183 meters, this multicolored marvel has grown undisturbed for 300 to 500 years, forming an intricate structure that supports a thriving ecosystem of marine life, including fish, crabs, and shrimps.
The coral, located in the biologically rich “coral triangle” of the western Pacific, was found during a National Geographic Pristine Seas expedition. Measuring 34 meters wide, 32 meters long, and over 5 meters tall, the coral initially appeared to be a shipwreck to the research team. Upon closer inspection, it was identified as a single, genetically identical colony of polyps that had expanded continuously over centuries.
“This is a significant scientific discovery, like finding the world’s tallest tree,” said Enric Sala, marine ecologist and founder of Pristine Seas. However, he warned that even this remote coral is vulnerable to threats such as global warming.
For the Solomon Islands, the discovery has deep cultural and ecological significance. Fisheries officer Ronnie Posala emphasized its importance, stating, “It reinforces the importance of our ocean, which sustains our communities, traditions, and future.” While coral reefs worldwide face degradation, this giant coral in slightly deeper waters offers a glimmer of hope. As Eric Brown, a coral scientist with the expedition, noted, “Witnessing this large healthy coral oasis in slightly deeper waters is a beacon of hope.”
