I love to get questions from visitors, and here's a great one from Caleb who came to the Tennessee Aquarium from Nashville, TN. Caleb asks, "Why do penguins put their fins out when they walk?" Well Caleb that's a great question. When walking, penguins use their flippers or wings for balance. So when you see a penguin in a big hurry on land, most of the time they will have their flippers out to the side and pulled slightly back to help with balance. Although somewhat clumsy on land, gentoos can out run a person over short distances. At Penguins' Rock you'll sometimes see them running for the pan of fish like the gentoos in the picture above.
