Fish migrating - [https://www.utahpeoplespost.com/wp-content/uploads/2014/10/Fish-Migrating-Poleward-as-Ocean-Temperatures-Increase.jpg]

Between May and July every year millions of small silver fish travel in vast shoals from the cold waters off South Africa’s Cape Point up to the coastlines of the northern Eastern Cape and southern KwaZulu-Natal. This annual event is called the Sardine Run.

The shoals are so big – 15km long, 3.5km wide and up to 40m deep – they can be seen by satellite. In their wake come hundreds of birds, sharks, whales, dolphins, all eager to feast.
