珊瑚白化压力：安达曼海蓝色珊瑚礁

ow Porites coral reef shows reef degradation, with vivid blue pigmentation on the hard coral, a stress marker linked to coral bleaching in the Andaman Sea. Blue colouration appears when coral loses symbiotic algae under heat stress, producing protective pigments in response, a sign the polyps remain alive.
