In the Agulhas

A Spinner Dolphin with an attached remora appears to have just pinned a fish in its mouth, while the dolphin on the right has just missed a leaping fish – Photo by Carl Safina. The Agulhas current flows down the east coast of Africa from the north. It’s described as “narrow, swift, and strong” on our briefing material aboard National Geographic Orion.

As it reaches the southern tip of Africa at Cape Agulhas (Cape of Good Hope is not actually the continent’s southern tip), it recirculates. Thus a major source of the current is the current itself.

In May to July millions and millions of Southern African Pilchards (Sardinops sagax) come to spawn in northbound water, forming the famous Agulhas Current sardine run. Schools can each be five miles long, a mile wide, and a hundred feet deep.

In the last few years some terrific footage of this phenomenal phenomenon has been filmed. Dolphins and schooling sharks rush the sardines as thousands of gannets rain from above.

It’s only March, but we got a tantalizing taste of the action in a mini-frenzy we happened upon today near Mossel Bay, South Africa. We had gannets, Spinner and Common Dolphins, several Bryde’s Whales, terns, and even a few African Penguins. It was quite a sight and we got to hang out near the action for a good while.
