Pingüino emperador

El pingüino más grande del mundo, el pingüino emperor puede medir hasta 1,2 metros de altura y pesar 45 kg, habitando el continente antártico en algunas de las condiciones más extremas de la Tierra. Se reproduce en la oscuridad del invierno a temperaturas inferiores a -60°C, con los machos incubando un único huevo sobre sus patas bajo una bolsa de cría durante 65 días mientras las hembras están en el mar. Su comportamiento de apiñarse —haciendo circular a los individuos a través del cálido centro de grupos de miles de ejemplares— es una obra maestra de la supervivencia cooperativa.
