海豹群

It is said that millions of sardines migrates from cold sea area for spawn in Capetown to the east for zooplanktons to prey. However, what wait for them are armies of predators, including of porpoies, doradoes, sharks, sea dogs and whales. Some solans and sea-gulls also dive into the sea to attempt to prey sardines, but sometimes they themselves become victims of sharks.

据悉，每年数以百万计的沙丁鱼将从开普敦较冷的产卵水域向东迁徙寻找浮游动物为食，然而等待它们的却是一群猎食大军，其中包括：海豚、剑鱼、鲨鱼、海豹和鲸，在水面之上还有塘鹅和海鸥盘旋着，试图寻找机会潜入水中捕食沙丁鱼，但有时潜入水中的鸟类也会成为鲨鱼的捕食对象。
