    • Emperor penguins are the largest of all penguins. These flightless animals live on the Antarctic ice and in the frigid surrounding waters.
    • Emperor penguins can weigh up to 40 kilograms (88 pounds).
    • Emperor penguins can dive deeper than any other bird—and stay under for more than 20 minutes!
    • Male and female emperors take turns going out to sea to eat. Females lay a single egg and then leave it behind. They go out hunting for two months, during which they eat fish, squid, and krill. Male emperors stay behind and keep the eggs warm. When the females return, they bring a full belly of food that they regurgitate for the newly hatched chicks. Meanwhile, the male emperors finally get their turn to go out and hunt for themselves.
