Barracuda Point

On the right morning, Barracuda Point is the single most astonishing fish encounter in Southeast Asia. Chevron barracuda in their thousands coil into a rotating cylinder over the shelf, a structure with apparent architecture that divers can hang beside until air, not interest, runs out. The supporting bill would headline anywhere else: grey reef sharks strafing the wall, whitetips stacked on the sand channel, bumphead parrotfish bulldozing past at dawn, turtles at nuisance density, and jacks mirroring the barracuda's geometry. Current makes the show and demands respect; guides read it, and divers follow their read.

その瞬間のために: The barracuda tornado, shark traffic in numbers, dawn bumphead parades

地形: Wall and current-swept shelf with a sandy channel

流れ（カレント）: The point works because water moves; expect brisk drifts and a washing-machine patch where flows meet.

エントリー: Permit-day boats stage from Mabul and Kapalai; entries are timed to the current around the island's northeast corner.

危険生物・リスク: Strong, converging currents and a wall that falls past 40 m; stay with the guide's line through the point.

許可証＆ルール: Dived only on an allocated Sipadan permit day.

保全: Inside Sipadan Island Park: permit-capped numbers, no gloves, no touching, no night diving.

ナイトロックス: ここでは効果的です——このエリアのプロファイルは、ナイトロックスが無減圧潜水時間を有意に延ばせる水深帯にあります（適切なトレーニングを受けていることが前提です）。
