Nature's Great Events S01E04 The Great Tide

Nature's Great Events S01E04 The Great Tide (540p, soft Eng subs)


A mighty army of dolphins, sharks, whales, seals and gannets hunt down the billions of sardines along South Africa's east coast each winter. This is the sardine run: an underwater armageddon, the greatest gathering of predators anywhere on the planet, and the most spectacular event in the world's oceans.


However, in recent years the sardine run has become less predictable, perhaps due to the warming effects of climate change. If the sardine run does not happen, the lives of the animals caught up in the drama hang in the balance.


Pioneering a unique boat stabilised camera mount for surface filming, the Nature's Great Events crew capture all the high-octane action as the predators compete for sardines, filmed with aerial, underwater and above water cameras. Super slow-motion cameras also capture the very moment gannets plunge into the water, hitting it at 60 miles an hour.


A violent winter storm is the trigger for the sardines to begin their desperate dash. They are followed by a superpod of 5,000 dolphins and further up the coast more predators gather. A shoal of sardines 15 miles long is pushed into the shallows and aerial shots show thousands of sharks gathering to feed on them.


The climax to the sardine run is a spectacular feeding frenzy as the dolphins round the sardines up into balls on which all the predators feast. Gannets rain down in their thousands, sharks pile in scattering the fish and a Bryde's whale lunges in taking great mouthfuls of sardines.
