Wall-top current aggregations of bigeye trevally form dense, rotating cylinders of several hundred fish that divers can swim inside. The school reforms around a stationary diver, creating one of the most immersive underwater photography experiences on the wall. In the afternoon, schools disperse and individuals scatter across the reef to hunt. Their abundance here reflects the intact food web that Tubbataha's World Heritage protection maintains.
