Migration: Predation

Journey to the east coast of Africa as dolphins, sharks, whales and birds converge to feast on migrating sardines, the greatest shoal on Earth.

Biology - Ecosystems - Learning Points.

From May to July, millions of sardines migrate to warmer waters around the coast of South Africa.

During the sardine run the shoals are trailed by a mass of predators, such as dolphin, sharks and whales.

Working together, dolphins use sonar to detect, encircle and trap the sardines creating a 'bait ball' at the ocean surface.

The bait ball attracts gannets, sharks and whales.
