Emperor penguins
swim in groups to increase their safety from predators. Comical on land,
they are transformed into jet fighter planes underwater, complete with
contrail. The contrails seen here are streams of bubbles. The emperor
penguin's thick feathers insulate it by trapping a layer of air next to
the skin, but often some of that air streams out when the bird swims.
