d buoyancy control and reef stewardship define cavern diving exploration inside a natural archway swim-through at Ko Haa, where juvenile gorgonian sea fans line the passage walls and sunrays stream through the opening ahead. Parrotfish and starfish are visible along the rocky floor. Disturbing the fragile octocoral growth lining this passage is a real risk, making an honest assessment of personal dive skills essential before entry. 4K, horizontal, wide angle, scuba diver POV. Ko Haa Archipelago, Andaman Sea, Krabi Province, Thailand.
