Greatest shoal on earth!

Every year millions of sardines swim from the frigid waters of South Africa's Cape Point northward along the country's east coast.

The sardines have a safety-in-numbers philosophy, but these stunning pictures show that it has its flaws. 

They capture a feeding frenzy near Port St Johns as dolphins, whales, Cape Gannet birds and fur seals gorge themselves on giant balls of fish.

They were taken by underwater photographer and marine enthusiast Greg Lecoeur, 37, who made the journey from his hometown on Nice, France, to document the migration, which happens in late-June each year.

In terms of biomass the run is equal to east Africa's world-famous great wildebeest stampede, which sees over two million of the animals head from the Serengeti National Park in Tanzania to the Maasai Mara National Reserve in Kenya in search of more verdant pastures.

The shoal can be nine miles long, 130 feet deep and two miles wide - so big that it can be seen from space.
