Sardines and Their Predators

In summer, sardines are far out at sea, prompting birds to travel long distances to find them. Birds dive from heights at high speeds to catch their prey, facing significant risks. They rely on dolphins to keep the sardines near the surface. However, the crowded environment poses collision risks.
