Nature The Oceans Greatest Feast (2022)

The sardine run is the largest biomass migration on the planet, rivaling the great herds of the Serengeti. Common dolphins are the keystone heroes of the sardine run, acting as orchestrators of feeding events for sardine predators, such as sharks, gannets, and whales. Orcas swim thousands of miles to intercept the sardine run and hunt dolphins, allowing sardines to swim away from their initial predators. LIKE and FOLLOW for more documentaries like these.
