Horse-eye jacks aggregate in tornadoes of several hundred individuals above Bajo Minalta's summit throughout the year, their silver bodies rotating in a disciplined cylindrical formation that divers can ascend through during safety stops. They are pursuit predators that use coordinated group behaviour to herd small fish against the current, then attack the compressed school from multiple directions simultaneously. The pinnacle's current-swept position concentrates both prey and predator in a small area, producing the dense aggregations that make this site one of the Rosario Islands' most dramatic dives.
