海洋野生动物行为：泰国珊瑚礁上的鹦嘴鱼群迁徙

ant blue terminal phase male Ember Parrotfish (Scarus rubroviolaceus) circles through his harem of reddish brown females as the school migrates across a shallow hard coral reef, defecating sand into the water column along the way. This protogynous species changes sex from female to male with age and size, and the resulting sand plume is a byproduct of large scale reef bioerosion. 4K, wide angle, vertical medium tracking shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
