Sharks
Grey Reef Shark
Carcharhinus amblyrhynchos · Cartilaginous fish — family Carcharhinidae
Grey reef sharks are the metronome of a healthy atoll pass: compact, counter-shaded, white-edged tail flicking as they hold station in ripping current, waiting on the tide. Drift into a Fakarava or Palau channel on the incoming flow and the school materializes ahead of you — first ten, then fifty, then a wall of gray bodies layered from the coral to the surface. They are more assertive than their blacktip and whitetip neighbors and enforce personal space with a famous arched-back display, one of the clearest pieces of body language in the shark world. Their abundance on protected atolls masks steep losses on fished reefs.

"상주종"은 해당 다이빙 포인트에서 대부분의 다이빙 시 만날 수 있다는 의미이며, "계절종"은 표기된 월에 안정적으로 출현한다는 뜻입니다. 그 외의 생물은 보너스로 여기세요 — 계획의 근거로 삼지 마세요.

한눈에 보는 최적의 달
이해하기
서식지: Current-swept passes, channel mouths, and outer-reef drop-offs; hangs in the flow where baitfish concentrate
범위: Indo-Pacific — Red Sea and East Africa through the Maldives, Southeast Asia, and Micronesia to the central Pacific atolls
행동 특성: The channel specialist. Greys stack in current like kites on strings, holding formation off atoll passes by the dozen or, at Fakarava, by the hundred. When genuinely cornered the species performs a distinctive agonistic display — back arched, pectorals dropped, exaggerated swimming — which is a clear instruction to back away slowly.
먹이: Reef fish, squid, and octopus, mostly hunted at night or in pass currents
크기: 보통 1.5 m; 최대 기록 수심 1.9 m (total length).
이 생물 주변에서의 행동 요령
Hook in or hold position at the pass edge rather than drifting into the school's core, keep out of the current line the sharks are working, never chase a displaying animal for a photo, and follow local rules on reef hooks.
보존
Assessed Endangered in 2020; strong site fidelity makes populations easy to fish out and slow to recolonize. Large no-take atolls in French Polynesia, Palau, and the Coral Sea now hold a disproportionate share of the species.
