Examining the hunting methods of aquatic predators. The vastness of oceans means that wildlife is scattered over a large area, and animals often have to travel great distances in search of food. Blue whales' great size proves useful in their search for krill, while frigate birds have developed a clever means of catching food without having to land on water.
