Researchers from the Central Marine Fisheries Research Institute (CMFRI) have photographed a natural coral formation beneath the sea that appears to resemble the Indian national tricolour. The unusual underwater image was captured during a marine mammal survey near Minicoy in Lakshadweep.
According to CMFRI, the formation consists of two coral colonies displaying orange, white and green colours. The species were identified as Lobophyllia corymbosa, which showed a vibrant orange colour, and Lobophyllia radians, which displayed white and green shades.
Beyond its striking appearance, the image has provided researchers with valuable insights into how corals respond differently to environmental stress. One colony of Lobophyllia radians had undergone bleaching after losing its symbiotic algae, while a neighbouring colony of the same species remained healthy despite being exposed to similar conditions.
CMFRI Director Grinson George said the difference in thermal stress tolerance could provide important insights for coral reef restoration and climate adaptation research.
The institute is also expanding efforts to restore marine ecosystems by deploying artificial reefs along coastal waters and replenishing depleted populations of ecologically and economically important marine species.
