Marine researchers have documented a giant living coral colony near Kadmat Island in Lakshadweep that could be among the largest known coral colonies in the world. Known locally as the “Potato Patch,” the coral belongs to the species Pavona clavus and covers an estimated 4,250 square metres—roughly half the size of an international football field. Scientists say the colony may be between 700 and 1,800 years old, although further scientific dating is needed to confirm its exact age.
The discovery was made during a marine biodiversity survey conducted by researchers from the Department of Science and Technology, the Research and Environmental Education Foundation (REEF), and conservation partners. Surveys found that nearly 58 percent of the coral tissue remains alive, indicating remarkable resilience despite repeated marine heatwaves, coral bleaching events, and tropical cyclones that have affected reefs across the Indian Ocean.
Scientists believe the ancient coral could provide valuable insights into coral longevity, climate adaptation, and reef resilience. Its survival over centuries makes it a natural archive of environmental change and an important resource for future marine research. The finding also highlights the ecological significance of Lakshadweep, India’s only coral atoll chain, which supports rich marine biodiversity, fisheries, tourism, and coastal protection.
Researchers plan continued monitoring of the giant coral colony to better understand how reefs can withstand growing climate-related pressures and to strengthen conservation efforts in the region.
