After laying her egg the female Emperor Penguin ditches the dad and heads to the seaside with her friends where she feasts. Left alone with the egg, dad protects it by balancing it on it's feet for 64 days. 120 mph bone chilling winds don't help the situation. Luckly all the fathers work together to keep their eggs warm and safe. If mom is late returning from gorging herself dad can cough up a morsel of protein and fat to keep his chick nourished. Apparently this is all he has left. He hasn't eaten in 115 days. Married life is hard work, the male will lose around half his body weight bringing his offspring into the world.
