Dhonfanu Thila

Dhonfanu Thila is where Baa's mantas go when they are not feeding in the bay. The pinnacle's coral heads work as cleaning stations through the season, and divers kneeling on the sand perimeter routinely watch two or three animals circle the blocks for an entire dive, wings tipping as wrasse move over their gills. The reef holds its own between passes (morays, sweetlips under the overhangs, turtles on the ledges), but nobody pretends the mantas are not the point. Guides run strict positioning so the animals keep station rather than leaving.

您此行的高光时刻: Season-long manta cleaning activity at kneeling-depth blocks

地形地貌: Coral pinnacle with cleaning blocks on its flanks and ledges cut into the sides

水流: Plankton-bearing current is what brings the mantas; expect green water on the best days.

危险因素: Reduced visibility in plankton blooms; multiple boats in season.

保育: Stay low, behind the guide's line, and let mantas control every approach.

高氧（Nitrox）: 在此值得使用：这些潜点的深度范围内，富氧空气（nitrox）能有效延长免减压停留时间，前提是您已接受相关培训。
