Big Fish
Dogtooth Tuna
Gymnosarda unicolor · Bony fish — family Scombridae
The dogtooth is the wolf of the drop-off — not a true bluefin-style tuna but a giant reef-bound mackerel with a mouthful of visible canines and a habit of appearing exactly where the wall meets deep water. Its presence is a mark of a healthy, current-washed reef; sites like Sipadan's corners, Osprey's North Horn, and Tubbataha's walls almost always hold one cruising the 30-meter line, chrome flanks flashing as it banks. Watching a big doggie hit a fusilier school from below, a detonation of scales in the blue, is one of wall diving's underrated spectacles. It grows slowly and holds territory, so heavily fished reefs go quiet of them fast.

"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: Steep outer-reef walls, seamounts, and current-swept channels — a reef-associated tuna rather than an open-ocean roamer
범위: Tropical Indo-Pacific from the Red Sea and East Africa through Indonesia and Micronesia to the central Pacific
행동 특성: A solitary or small-group hunter that patrols the blue edge of walls with slow menace, then vanishes upward through a baitball in a silver blur. Divers meet it hanging in current at channel mouths or rising curiously toward bubble streams — a long, pale torpedo with a line of visible teeth even at rest.
먹이: Schooling reef and mid-water fish — fusiliers, rainbow runners, small trevally — taken in high-speed vertical ambushes
크기: 보통 1.0 m; 최대 기록 수심 2.0 m (total length; trophy fish exceed 80 kg).
이 생물 주변에서의 행동 요령
Nothing special beyond the usual: hold your line in the current, no feeding, and let the fish make its inspection pass without pursuit.
보존
Least Concern but slow-growing and site-attached for a scombrid, and prized by spearfishers — abundance now tracks protection closely.
