Where You Will See It In Cozumel
Mid-water off the wall at Santa Rosa, Palancar and Punta Sur, usually seen looking away from the reef rather than at it.
Reliable sites: Santa Rosa Wall, Palancar Caves, Punta Sur.
Behaviour
Schooling predators that use the current line. Schools compress and flash when they turn, which is the moment most divers notice them.
Commonly Confused With
- Bar jack — Bar jack has a black-and-blue stripe running along the back and into the lower tail lobe, and is usually solitary or in pairs.
- Crevalle jack — Crevalle has a blunter head and a black spot on the pectoral fin.
Diving Etiquette And Safety
Nothing required. Look away from the reef during a drift — most divers miss them by staring at coral.
