Checkerboard Wrasse On Reef Ledge With Gorgonian Sea Fans And Red Macroalgae - 4K stock video
A checkerboard wrasse (Halichoeres hortulanus) moves along a reef ledge in the Andaman Sea as red macroalgae (Rhodophyta spp.) visibly colonises the branches of gorgonian sea fans, an indicator of coral stress associated with elevated sea temperatures, ocean acidification and nutrient runoff. When gorgonian tissue is weakened or dying, opportunistic macroalgae colonise the exposed skeleton, accelerating deterioration. Brain coral, encrusting coralline algae and a large gorgonian fan in advanced algal overgrowth are visible in the same frame. 4K, horizontal, wide diver POV. Andaman Sea, Krabi Province, Thailand.
