Celebrated on April 25th
Did you know: Emperor Penguins are the tallest species, standing nearly 4 feet tall. The smallest is the Little Blue Penguin, which is only about 16 inches. Fossils place the earliest penguin relative at some 60 million years ago, meaning an ancestor of the birds we see today survived the mass extinction of the dinosaurs.

They huddle together to escape wind and conserve warmth. Individuals take turns moving to the group’s protected and relatively warn interior. Once a penguin has warmed a bit it will move to the perimeter of the group so that others can enjoy protection from the icy elements.

This technique is called as “porpoising”. Smaller penguins don’t dive as deep as the bigger ones because they are weak and their bones are air-filled. Unlike small penguins, big penguins’ bones are solid and Emperor penguins can dive to a depth of 1,870 feet and can remain in water for about 22 minutes.
