Manta Point (Nosy Be)

Local operators run a deeper offshore bank west of Nosy Be under the name Manta Point, dived mainly in the spring season when plankton draws big filter feeders to the area. Mantas visit its cleaning stations, though far less predictably than at famous stations elsewhere in this ocean — this is a hopeful dive rather than a scheduled appointment, and honest shops sell it that way. The bank itself holds reef sharks on some days, passing eagle rays, and solid fish life over the coral heads. Details in print about the site are thin; treat depths and conditions as the operator briefs them.

その瞬間のために: Seasonal chance of mantas at an offshore cleaning bank

地形: Offshore reef bank with cleaning-station coral heads

流れ（カレント）: An exposed outer bank; operators time it around the calmer dry-season windows.

危険生物・リスク: Open-water exposure and current on the bank.

保全: Standard manta-station etiquette applies on the days it pays off: low, still, and out of the animals' lane.
