泰国泡沫珊瑚早期白化

ble corals (Plerogyra sinuosa) on an Andaman Sea reef show an early stage coral bleaching contrast, the foreground colony displaying pale, ghostly white vesicles against the fuller colour of the colony behind. Thermal stress causes bubble coral to expel its symbiotic zooxanthellae algae, stripping colour and nutrition in a process fatal to the colony if sea temperatures do not drop. Threespot dascyllus (Dascyllus trimaculatus) move through the frame. 4K, vertical, wide angle, scuba diver POV. Ko Haa, Andaman Sea, Krabi Province, Thailand.
