Penguins: The Tuxedoed Travelers of Ice and Snow | 4K UHD Documentary

Penguins may look clumsy on land, but beneath the surface, they are some of the ocean’s most skilled hunters. From emperor penguins that dive deeper than submarines to tiny little blue penguins that stand just a foot tall, these birds are full of surprises. In this 4-minute documentary, we explore how penguins survive in some of the harshest places on Earth — from icy Antarctic blizzards to the deep, freezing ocean.
