This competition and collaboration for food, in this case for a shoal of sardines, is an incredible sight: A sardine feeding frenzy featured in BBC’s The Hunt, narrated by Sir David Attenborough.

Sea lions swim in a graceful herding process that keeps the sardines at the water’s surface. Tuna and shearwaters, seabirds that can swim proficiently underwater, join. They make it increasingly difficulty for the sardines to stay together in their protective ball formation. Copper sharks soon smell the blood in the water and common dolphins join the frenzy before the arrival of a Bryde’s whale.

Pair this vid with The World of Food Chains with Max Axiom, Super Scientist, a book from one of our favorite science series for kids.
