Not all the penguins live in cold places.African penguins live in the south of Africa.Like other penguins,African penguins spend most of the day feeding in the ocean,and that helps keep them cool.
Most other penguins lay their eggs in the open.However,African penguins do it in a different way.They dig holes to lay their eggs so that they are protected from the sun's heat (高温).The baby penguins stay in the holes for about three weeks.After that,they start going out and return to the holes to stay cool and stay away from dangerous animals.On land,some animals such as dogs and cats will eat penguins.
African penguins are in danger now.There are only about 52,000 left in the wild.One problem is that they are losing their homes.Other problems include humans' picking penguin eggs for sale,competition with humans for fish,and oil pollution in the ocean.
