Bigeye trevally form massive rotating bait balls around the submerged pinnacles of the Tablas Strait, their silver bodies catching the current-filtered light in synchronized flashes. These schools can number in the thousands and are a magnet for tuna, sharks, and dolphins that sweep through to hunt. The trevally aggregations are largest and most spectacular during flood tide when zooplankton concentrations peak.
