Jacks at Barracuda Point

More than three hundred bigeye trevally (Caranx sexfasciatus) circled for hours in a large school that looked more like a tornado when seen from a distance. They swam for hours like this, aside from one hectic flurry of activity to avoid an approaching shark. Photographed at Barracuda Point off the shore of Mary Island in the Solomon Islands.
