Happy World Penguin Day!

Every year on April 25, the world celebrates the existence and beauty of penguins.

The day isn't limited to any specific species of penguins. There are 17 different species of penguins in the world, although the African and Humboldt penguins are the most common in the U.S., according to Nothing But Penguins.

To celebrate, the World Penguin Day website says to "find out more about penguins, explore what others have to say about penguins, tell your friends about penguins, send a penguin ecard, play penguin games and share the penguin love."
