Orcas (Orcinus orca) show their smarts by working together to whip up a meal. Here, a pod hunts for herring in Norway’s Andfjorden. Members of the pod coordinate their moves, herding a mass of herring into a manageable ball. They then whip their tails against the ball, stunning or killing the fish.
