Coral sighting in Lakshadweep offers clues to climate resilience

Scientists at the ICAR-Central Marine Fisheries Research Institute (CMFRI) have observed a rare formation of orange, white, and green corals off Minicoy in Lakshadweep. The sighting includes Lobophyllia corymbosa, which appears in vibrant orange, and Lobophyllia radians, which displays white and green hues.

Researchers are particularly interested in two neighboring colonies of L. radians that responded differently to the same environmental conditions. While one colony has undergone bleaching due to the loss of symbiotic algae, the other remains healthy and green. This natural comparison provides insights into thermal stress tolerance and why certain corals withstand rising sea temperatures better than others.

CMFRI Director Dr. Grinson George noted that the observation highlights both the resilience and vulnerability of marine biodiversity to climate stress. The findings may assist in coral reef restoration and climate adaptation research. Additionally, the institute is increasing efforts to deploy artificial reefs to revive degraded coastal habitats.
