Migration: Predation

The video explains the annual sardine migration from Antarctic waters to the East Coast of South Africa, occurring from May to July. Sardines follow phytoplankton and are pursued by predators like dolphins, birds, sharks, and whales. The migration begins in June, with sardines trapped in cold water corridors. Predators use strategies like creating bait balls to hunt sardines. The migration attracts thousands of predators, and as warm currents return, sardines head back to the Antarctic, with predators following.
