African penguins live in large colonies and spend their days at sea feeding and their nights gathered together on shore. Their diet consists of small fish such as sardines and anchovies, as well as small crustaceans and squid. Each penguin eats about one pound of fish per day. They absorb water as well as nutrients from their diet, but also are adapted to drink salt water. All penguins have highly developed glands over their eyes which filter salts out of sea water.
Predators of African penguins are sharks, Cape fur seals, and occasionally killer whales.
