礁石上的巨藻生态：泰国安达曼海的红羽藻

y of red sea plume algae (Asparagopsis taxiformis) fills a horizontal medium shot on a shallow Andaman Sea reef, its dense fronds tipped with pale blue warning colouration. Also known as limu kohu, this native Indo-Pacific alga produces a reactive chemical compound thought to deter grazing fish, a defence that allows it to persist as an established patch of reef macroalgae. 4K, wide angle, horizontal medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
