It is often funny to watch penguins on land because their bodies look fat and uncomfortable. But in the water it is very different. Penguins stopped flying and began to live in the water about fifty million years easily over their bodies, and this means they can travel very fast; as much as twenty-four kilometres per hour. They can also travel a long way. Emperor penguins, for example, can stay at sea for a month and travel almost 1,600 kilometres
