巨型皇冠丽蚌在泰国安达曼海健康的珊瑚礁上滤食

d giant clam (Tridacna squamosa) sits embedded in a healthy coral reef in the Andaman Sea, its rippled shell edge open to expose the fleshy mantle inside. Giant clams act as natural water filters, drawing in seawater and straining out plankton, helping maintain water clarity across the reef. The species also hosts photosynthetic algae within its mantle tissue, giving it a secondary energy source linked to the reef's wider nutrient cycle. 4K, wide angle, vertical medium shot, scuba diver POV.
