安达曼海珊瑚礁上的水下竖琴珊瑚和羽星

ral (Ctenocella pectinata), also known as lyre sea fan, extends vivid red comb-like branches on an Indo-Pacific reef while hosting a black feather star (Colobometra perspinosa) clinging to its upper structure. This reef biodiversity and marine symbiosis signal a healthy coral reef ecosystem in the Andaman Sea. Harp coral is acutely sensitive to reef degradation, making intact specimens a marker of reef health. Copy space above in blue water. 4K, vertical, medium shot, scuba diver POV.
