National World Penguin Day 2025 Theme. The sight of a small penguin waddling around in its icy homeland is truly endearing. There are 18 species of penguins, and all their natural habitats are in the southern hemisphere.
They walk around in tuxedos, they have a cute waddle, and they’re unique! April 25 is world penguin day, a celebration of one of the most charming and unique animal species in the world.
