sentence: Emperor penguins spend most of their time in the water, coming to the shore to breed.
sentences_after: There is nothing on the ice to make a nest, so after the female lays her one egg in winter, the male puts the egg on his feet to keep it warm until spring. This can be from 65 to 75 days. He has a special fold of skin on his stomach which can fold over and cover the egg to keep it warm. He does not eat during this time, and can lose up to half his weight. To keep warm, all the male penguins huddle together.
