Video by joelsartore / The largest of all living penguin species, the emperor penguin stands just under four feet tall (about 1.2m) and can weigh up to 88 pounds (40kg). Despite their large size, their aerodynamic build and strong flippers make them excellent swimmers, capable of reaching speeds of seven miles per hour (11kph) and diving as deep as 1,850 feet (560m) below the surface.
