泰国，白化的珊瑚骨架上野生的荆棘海星

f thorns starfish (Acanthaster planci) grips a coral colony stripped of living tissue, a visible marker of reef degradation and coral predation in the Andaman Sea. Digestion occurs externally, the stomach extruded over the coral surface to dissolve polyp tissue and leave the skeleton bone white. Outbreaks of this species are linked to nutrient runoff and rising sea temperatures, both intensifying pressure on Indo-Pacific reef ecosystems. 4K, wide angle, horizontal, medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
