Monad Shoal

Monad Shoal is the world's most dependable window on the pelagic thresher shark, an animal that otherwise lives beyond diver depth. At dawn, threshers rise onto this drowned island's plateau to visit cleaning stations, and divers kneel behind rope lines in gray-blue early light as sharks with scythe tails carve slow circles meters away, sometimes joined by devil rays or a passing manta. The ritual is regulated: fixed descent lines, no strobes without permits, no crossing the ropes. Between passes the shoal itself is plain, which nobody minds. You are there for one of diving's great appointments, kept more mornings than not.

Khoảnh khắc bạn đến vì nó: Thresher sharks at cleaning stations most dawns, occasional rays, a genuinely unique spectacle

Địa hình: Plateau of rubble and coral heads rimmed by drop-offs

Dòng chảy: Usually gentle on the plateau; the exposed edges catch more flow.

Điểm vào: Boats leave Malapascua around 5 a.m. to reach the shoal by first light; descents follow fixed lines to the viewing areas.

Nguy hiểm cần lưu ý: Repetitive 20 m dawn profiles on consecutive days; monitor no-deco time while watching the blue.

Giấy phép & quy định: Per-diver marine protected area fee collected by operators.

Bảo tồn: A locally protected area funded by diver fees; rope-line and lighting rules exist because the sharks abandon harassed stations.

Nitrox: Đáng dùng ở đây — các hồ sơ nằm trong khoảng độ sâu mà nitrox có thể kéo dài thời gian không dừng một cách thực sự có ý nghĩa (khi đã được đào tạo sử dụng).
